hardening treatment
1Hardening (disambiguation) — Hardening has several uses:* In computing, hardening is the process of securing a system. This work is especially done to protect systems against hostile environments or attackers. * In metallurgy, hardening is the strengthening of metal alloys… …
2hardening — increasing the hardness of steel by heat treatment. This normally implies heating the steel to a required temperature and quenching in a suitable medium, e.g., oil or water. age hardening case hardening cyanide hardening flame hardening induction …
3Hardening (metallurgy) — In metallurgy, hardening describes techniques to increase the hardness of a material. There are five main hardening mechanisms: * Hall Petch hardening, a hardening that result due to a decrease in grain size. * Cold working, also called strain… …

5hardening — /hahr dn ing/, n. 1. a material that hardens another, as an alloy added to iron to make steel. 2. the process of becoming hard or rigid. [1620 30; HARDEN + ING1] * * * In metallurgy, an increase in hardness of a metal induced, deliberately or… …
6Heat treatment — is a method used to alter the physical, and sometimes chemical, properties of a material. The most common application is metallurgical. Heat treatments are also used in the manufacture of many other materials, such as glass. Heat treatment… …
7Precipitation hardening — Precipitation hardening, also called age hardening, is a heat treatment technique used to increase the yield strength of malleable materials, including most structural alloys of aluminium, magnesium, nickel and titanium, and some stainless steels …
8Induction hardening — is a form of heat treatment in which a metal part is heated by induction heating and then quenched. The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Induction hardening is used to… …
9Cryogenic hardening — is a cryogenic heat treating process where the material is cooled to approximately −185 °C (−301 °F), usually using liquid nitrogen. It can have a profound effect on the mechanical properties of certain steels, provided their composition and …
10Cryogenic treatment — A cryogenic treatment is the process of treating workpieces to cryogenic temperatures (i.e. below −190 °C (−310 °F)) to remove residual stresses and improve wear resistance on steels. The process has a wide range of applications from… …
