A futures market that is slowly advancing in prices. A hard drive, also known as a hard disk drive, is a storage device used on many computers that's prone to failure but offers high performance. Age hardening is a type of heat treatment used in metallurgy to strengthen metal alloys. It means that the material becomes hard and strong once it is strained. Hard water minerals such as magnesium (Mg) and Calcium (Ca) react with the resin and exchange places with the sodium ions (Na) leaving the outgoing water with sodium ions instead of hard water causing minerals. Hardening (metallurgy), a process used to increase the hardness of a metal Hardening (botany) or cold hardening, a process in which a plant undergoes physiological changes to mitigate damage from cold temperatures Hardening (computing), the process of securing a system against attack Target … Depressed is a state or condition of a market characterized by slumping prices, low volume, and lack of buyers. In the late 1980s, though, brands like Zima® became popular. Combined with a subsequent hardening operation the desired component properties can be varied to suit the application. Strain hardening is a process in which metals harden when flexed mechanically. In these periods of fiscal “hardening," consumers and market participants alike will often complain that approval criteria have become unnecessarily onerous. It is also called precipitation hardening, as it strengthens metal by creating solid impurities, or precipitates, in the alloy that prevents dislocations in the alloy's crystalline structure. Carburizing. Flame hardening is a rapid, economical method for selectively hardening specific areas on the surface of a part. More rigorous underwriting or lending practices are sometimes implemented in response to risky decisions by the financial institutions involved, such as the optimistic derivative contracts and subprime loan agreements that American banks and insurance companies entered into prior to the 2007-2008 financial crisis. https://www.thefreedictionary.com/hardening, These processes can be to treat the whole gear or just focused on the teeth themselves and among the most common are carburizing, induction, The influence of strain-path changes on flow stress and work, "The adhesive also has to be very reactive and harden quickly during joining." Although this reversal in sentiment amongst financial institutions–from risky to more conservative–can help reduce the incidence of inappropriate insurance policies and too risky loans, it can also make it difficult for creditworthy counterparties to secure credit or insurance. A ‘hardening period’ is the term used to describe the period of time during which security is liable to be set aside if the company (the entity granting the security) enters into insolvency proceedings. The material develops a higher level of hardness when it is cooled at a rate fast enough to lock in the transformation. Hardening is the process of identifying and securing information security vulnerabilities. Age hardening is a heat-treatment process used to strengthen metal alloys. Reducing available ways of attack typically includes changing default passwords, the removal of unnecessary software, unnecessary usernames or logins, and the disabling or removal of unnecessary services. In the aftermath of this financial crisis, financial firms were more keen to reset their lending and underwriting standards on a more conservative footing. Precipitation hardening is a method that makes use of heat application to a pliable material, like metal alloy, to make it tougher. There are many aspects to securing a system properly. This is the result of work or strain hardening. Strain hardening is a process that takes place in the crystal lattice of a material. The term hardening can also be used in the insurance and banking industries to refer to a period of more stringent underwriting or lending standards. Case hardening is the process of hardening the surface of a metal by infusing elements into the material’s surface, forming a thin layer of harder alloy. These periods often arise following a financial shock such as the credit crunch that occurred during the 2007-2008 financial crisis. There are many aspects to securing a system properly. Strain hardening is a process in which metals harden when flexed mechanically. Thermal spraying, spray-fuse and welding processes are generally used to apply the hardfacing layer. Protection is provided in various layers and is often referred to as defense in depth. After quenching, the heated metal is converted into martensite. Linux Systems are made of a large number of components carefully assembled together. Hardening (metallurgy), a process used to increase the hardness of a metal Hardening (botany) or cold hardening, a process in which a plant undergoes physiological changes to mitigate damage from cold temperatures Hardening (computing), the process of securing a system against attack The offers that appear in this table are from partnerships from which Investopedia receives compensation. This process is applied to selected metal surfaces of carbon and alloy steels, cast and ductile irons and some stainless steels, followed by an appropriate quenching method. n. 1. How to use hardening in a sentence. ,K, fluctuate only little. Work hardening, in metallurgy, increase in hardness of a metal induced, deliberately or accidentally, by hammering, rolling, drawing, or other physical processes. Under these circumstances, even small fluctuations in price can have a tremendous impact on the owner of a highly-leveraged futures position. The result of flame hardening is a hard surface that is more resistant against wear and corrosion. Hardening is the process by which something becomes harder or is made harder.. Treatments may vary, but doctors usually prescribe cholesterol and blood pressure medications and recommend lifestyle changes. (My house has just 30 doors and windows, by comparison.) Channel hardening is a phenomenon where the norms of the channel vectors {g_k} k = 1, . ,K, fluctuate only little. Thermal spraying is preferred for applications requiring minimal thermal distortion of the component and good process control. Case hardening and surface hardening each have their benefits. So the system hardening process for Linux desktop and servers is that that special. Case-hardening or surface hardening is the process of hardening the surface of a metal object while allowing the metal deeper underneath to remain soft, thus forming a thin layer of harder metal (called the "case") at the surface. The advent of induction heating has made it possible to use electromagnetic energy that generates heat within the metals without taking up a lot of space or generating a lot of excess heat outside of the metal object that is being treated itself. Hard Link: A hard link is a link that directly associates a name with a given file in an operating system. Hardening and tempering. Define hardening. This rapid cooling forms a material microstructure that is hard and strong. Hardening describes conditions of rising prices and falling volatility in a particular market. The goal is to enhance the security level of the system. Hardening is popular among those who want to increase the hardness of the metal for strength and durability. In computing, hardening is usually the process of securing a system by reducing its surface of vulnerability, which is larger when a system performs more functions; in principle a single-function system is more secure than a multipurpose one. Hardening Period. In this hardening process, the metal part is passed through induction heating and then through quenching. The hardening process involves heating steel or iron above a critical temperature and then holding it there long enough for molecular transformation to occur. Example, bending the thin steel rod becomes more difficult the farther the rod is bent. technique in which the metal surface is reinforced by the adding of a fine layer at the top of another metal alloy that is generally more durable Induction hardening is a type of surface hardening in which a metal part is induction-heated and then quenched.The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. An increasing stress is required to produce additional plastic deformation and the metal apparently becomes stronger and more difficult to deform. Both processes are used hand in hand when hardening steel. Example, bending the thin steel rod becomes more difficult the farther the rod is bent. Hardfacing is the deposition of thick coatings of hard, wear-resistant materials on a worn or new component surface that is subject to wear in service. hardening synonyms, hardening pronunciation, hardening translation, English dictionary definition of hardening. Case hardening is a heat treatment technique in which the steel surface is processed by the addition of carbon. However, very often, this process leaves the steel very brittle and susceptible to breaking during use. Something that hardens, as a substance added to iron to yield steel. Various types of hard chrome include micro-cracked chromium, micro-porous chromium, porous chromium and crack free chromium. Its name comes from the point in the hardening process in which the metal is aged, either by heating it for an extended of time or … By way of example, equity margin requirements are generally around 50%, whereas margins as low as 5% to 10% are common for futures contracts. Cold rolling is the most common method of work hardening. These investments are characterized by a high degree of safety and relatively low rates of return. The goal is to enhance the security level of the system. Meaning of Strain hardening is self explanatory. 2. Strain hardening is a process that takes place in the crystal lattice of a material. Hardening is a metallurgical metalworking process used to increase the hardness of a metal. Precipitation hardening, also called age hardening or particle hardening, is a heat treatment technique used to increase the yield strength of malleable materials, including most structural alloys of aluminium, magnesium, nickel, titanium, and some steels and stainless steels.In superalloys, it is known to cause yield strength anomaly providing excellent high-temperature strength. The hardness of a metal is directly proportional to the uniaxial yield stress at the location of the imposed strain. An increasing stress is required to produce additional plastic deformation and the metal apparently becomes stronger and more difficult to deform. The temperature at which austentizing rapidly takes place depends upon the carbon content in the steel used. The vmWare guide for vSphere 5 highlights 60 critical security items that must be checked; For Windows 2008, the Microsoft guide for minimal system hardening includes 158 settings that need to be immediately secured out of the box (it’s is a big house). This process is applied to selected metal surfaces of carbon and alloy steels, cast and ductile irons and some stainless steels, followed by an appropriate quenching method. Once the temperature is reached, it is rapidly cooled by a quenching media. Here's what the 75Hard Challenge really entails, including the pros and cons. Hardening definition is - sclerosis.

Carburizing is one of the types of the heat treatment processes and it is also called as … Strain Hardening is when a metal is strained beyond the yield point. Server Hardening is the process of enhancing server security through a variety of means which results in a much more secure server operating environment. Ferrous iron may also be present; oxidized to the ferric form, it appears as a reddish brown stain on washed fabrics and enameled surfaces. Server Hardening is the process of enhancing server security through a variety of means which results in a much more secure server operating environment. 3. This could be especially damaging for owners of options contracts set against those commodities, whose value generally falls when the volatility of their underlying asset decreases. Hardening Hardening involves heating of steel, keeping it at an appropriate temperature until all pearlite is transformed into austenite, and then quenching it rapidly in water or oil. Protecting in layers means to protect at the host level, the application level, the operating system level, the user level, the physical level and all the sublevels in between. Hard lemonade is a form of alcopop, a flavored malt beverage with about the same alcoholic content as bottles of beer. Surface hardening is the process of hardening the surface of a metal object while allowing the metal deeper underneath to remain soft, thus forming a thin layer of harder metal (called the "case") at the surface. The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. The two part process begins with hardening the steel so that it becomes hard and does not wear over time. For many traders, a market that is hardening presents ideal conditions for trading because of the apparently calm and predictable nature of the market at such times. Unlike a soft link, which changes the pointer when the file is renamed, a hard link still points to the underlying file even if the file name changes. The money market refers to trading in very short-term debt investments. The goal of the 75 Hard Challenge isn’t to improve your mental toughness, it’s to motivate you to unconsciously spread his name, his brand, and his supplement company to your friends. Examples of cold-rolled products include steel sheets, strips, bars, and rods. Hard Link: A hard link is a link that directly associates a name with a given file in an operating system. Systems hardening is a collection of tools, techniques, and best practices to reduce vulnerability in technology applications, systems, infrastructure, firmware, and other areas. Read this first. Surface hardening, treatment of steel by heat or mechanical means to increase the hardness of the outer surface while the core remains relatively soft. Frequently, the term "hardening" is associated with tempered steel. System hardening is the process of doing the ‘right’ things. Hardening off allows plants to adapt from being in a protected, stable environment to changeable, harsher outdoor conditions. Induction hardening has several benefits over other hardening methods. (My house has just 30 doors and windows, by comparison.) When atherosclerosis in the brain progresses to the point that plaque … In metallurgy: Hardening treatments …what is known as solid-solution hardening, but the alloy can usually be hardened appreciably more by aging to allow a very fine precipitate to form. Laser hardening consists of the rapid heating of a material’s surface by laser beam, a short hold at the target temperature, and intensive cooling due to the high thermal conductivity of the material. hardening and tempering Heat treatment of steel in a school workshop is normally a two stage process. The process of induction hardening is fairly straightforward, but it requires specialized equipment. The act or process of becoming hard or harder. Although plants usually recover eventually, hardening off is thought to be preferable to a sudden shock. A hard disk drive (sometimes abbreviated as a hard drive, HD, or HDD) is a non-volatile data storage device.It is usually installed internally in a computer, attached directly to the disk controller of the computer's motherboard.It contains one or more platters, housed inside of an air-sealed casing.Data is written to the platters using a magnetic head, which moves rapidly over them as they spin. The term hardening is also common in the insurance and lending industries, where it refers to periods of time when more rigorous underwriting or lending practices are implemented. Let us look at following stress-strain curve: As we can see that a body is loaded from point O beyond its yield limit (until it reaches the plastic zone) and thus deformed plastically. Have you thought about trying the 75Hard Challenge? A harder metal will have a higher resistance to plastic deformation than a less hard metal. Hardening of the arteries, also known as atherosclerosis, is a condition that develops when fat and other matter called plaque develops along the walls of the arteries. Of course, for traders wishing to speculate on large movements in commodity prices, a hardening market might be a negative sign, as the resulting decline in volatility could make those large moves less likely to materialize. System hardening is the process of doing the ‘right’ things. This is due to the advanced security measures that are put in place during the server hardening process. Strain Hardening is when a metal is strained beyond the yield point. Hardening may refer to: . Yet, the basics are similar for most operating systems. As more plaque builds up and hardens in the arteries, the heart has to work much harder to deliver blood throughout the body. This form of hardening is useful to increase the strength of metals that cannot be hardened by … As it moves through the rollers and is compressed, the metal grains are deformed. Also known as strain hardening, work hardening is a process that makes it possible to increase the strength of a metal component with the use of what is known as plastic deformation.Some metals and metal alloys, such as aluminum or copper, are most efficiently strengthened using this particular approach.The essential process involves the creation of specific dislocation movements … Hardening may refer to: . Alloy steels are normally case hardened to increase the metal characteristics. Induction hardening is one of the type of the surface hardening processes. It occurs both as an internal process of security testing and as a result of being exposed to information security attacks. Yet, the basics are similar for most operating systems. A Hardening Sprint is a specialized sprint dedicated to stabilizing the code base so that it is robust enough for release; it is often necessary because the Team failed to use an appropriate Standard of Care when it did its work. In commodities trading, a market is said to be “hardening” if its prices are steadily rising at a time when volatility is relatively low. Hard water, water that contains salts of calcium and magnesium principally as bicarbonates, chlorides, and sulfates. This is due to the advanced security measures that are put in place during the server hardening process. Hard water passes through a cylinder inside the water softener containing ion exchange resin beads packed with sodium ions (Na).

Hardening is the process by which something becomes harder or is made harder.. Case hardening of steel is used for numerous applications including for the manufacture of carbon steel forgings and carbon steel pinions. In these industries, hardening is commonly used to refer to periods of more rigorous underwriting or lending standards. It is essential that the micro-cracked and porous coatings have a minimum thickness between 80 … These researchers suggest that futures markets are considered volatile not because of price fluctuations, but because of a great deal of leverage available to futures traders. All content on this website, including dictionary, thesaurus, literature, geography, and other reference data is for informational purposes only. A commonly held belief is that the rise of speculators into the commodities futures markets has led to an increase in price volatility on futures contracts. A money market fund is a type of mutual fund that invests in high-quality, short-term debt instruments and cash equivalents. The hardening guide for Oracle Solaris v11 has 55 of these critical configuration items. If suddenly placed outside, the shock can severely check a plant's growth. Although the first few deformations imposed on metal by such treatment weaken it, its strength is increased by continued deformations. . Flame hardening is a rapid, economical method for selectively hardening specific areas on the surface of a part. It is easier to control b ecause it is an electrical process rather than a … The hardening guide for Oracle Solaris v11 has 55 of these critical configuration items. In the finance industry, the term “hardening” is typically used to refer to a period of rising prices and reduced volatility, specifically in the commodities trading industry. Hardening of the arteries in the brain or other parts of the body is known as atherosclerosis, and it is typically caused by an accumulation of LDL cholesterol in the arteries, WebMD reports. Early forms of alcopop included wine coolers, which used wine instead of malt. Induction hardening is used to selectively harden areas of a part or assembly without affecting the properties of the part as a whole. The goal of systems hardening is to reduce security risk by eliminating potential attack vectors and condensing the system’s attack surface. From Wikipedia, the free encyclopedia Induction hardening is a type of surface hardening in which a metal part is induction-heated and then quenched. Using a Hardening Sprint is not recommended and the need for it should be addressed by improving engineering practice. Channel hardening is a phenomenon where the norms of the channel vectors {g_k} k = 1, . Futures/Commodities Trading Strategy & Education. Strain hardening is closely related to fatigue. In metallurgy, age hardening is a heat treatment technique used to increase the hardness of an alloy by a relatively low-temperature heat treatment that causes precipitation of components or phases of the alloy from the supersaturated solid solution. Hardening is most commonly applied when referring to the commodities futures market. Case hardening is a simple approach that hardens the surface of a material by infusing elements into the metal. Unlike ordinary tempering, alloys must be kept at elevated temperature for … 2. A hedge is a type of investment that is intended to reduce the risk of adverse price movements in an asset. Strain hardening is closely related to fatigue. Hardening refers to providing various means of protection in a computer system. Precipitation hardening, also referred to as age hardening, is a technique where heat is applied to a malleable material, such as a metal alloy, in order to strengthen it.The technique hardens the alloy by creating solid impurities, called precipitates, which stop the movement of dislocations in the crystal lattice structure. Work hardening, is the strengthening of a metal by plastic deformation. Thickness of hard chrome plating ranges from 2 to 250µm. This technique gives strength to alloys by hardening them and adding fine, solid impurities known as precipitates. This information should not be considered complete, up to date, and is not intended to be used in place of a visit, consultation, or advice of a legal, medical, or any other professional. Atherosclerosis -- or hardening of the arteries -- is the leading cause of heart attacks, strokes, and peripheral vascular disease. In the banking and insurance industries, hardening is often observed in the aftermath of financial crises when financial institutions are more eager to control and reduce their risks. A term used to describe a price of commodity or futures contracts that is gradually stabilizing. Induction hardening takes place through mutual induction (transformer)which means the induction coil act as primary and secondary is the metal to be hardened. Against actual is an exchange between commodities traders of a cash position in a certain commodity for a futures contract for the same commodity. We say that the propagation offers channel hardening if This form of hardening is useful to increase the strength of metals that cannot be hardened by heat treatments. For example, if a high carbon steel or silver steel screw driver blade has been manufactured, at some point it will have to be ‘’hardened’ to prevent it wearing down when used. Unlike a soft link, which changes the pointer when the file is renamed, a hard link still points to the underlying file even if the file name changes. Laser hardening is a surface-hardening process commonly used for complicated shapes or large objects because it allows for absolute control on the surface hardness and texture. Hard chrome plating is an electroplating process in which chromium is deposited from a chromic acid solution. Induction hardening heats a material using a form of induction heating to a specific temperature. On the contrary, some researchers have concluded that an influx of futures traders, and the liquidity that they bring to the market, has a stabilizing or hardening effect on futures prices. Flame hardening is a common surface hardening method.Metal surfaces, such as steel, are heated with a high-temperature flame and then quenched. We say that the propagation offers ,K, fluctuate only little. In the plastic region, the true stress increases continuously, meaning that when a metal is strained beyond the yield point, more and more stress is required to produce additional plastic deformation and the metal seems to have become stronger and more difficult to deform.
