Hardening (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… … Wikipedia
Induction 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… … Wikipedia
Cryogenic 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 … Wikipedia
Diffusionless transformation — Diffusionless transformations classifications A diffusionless transformation is a phase change that occurs without the long range diffusion of atoms but rather by some form of cooperative, homogeneous movement of many atoms that results in a… … Wikipedia
induction hardening — a widely used process for the surface hardening of steel. The components are heated by means of an alternating magnetic field to a temperature within or above the transformation range followed by immediate quenching. The core of the component… … Mechanics glossary
