Heat treatment
cyaniding
Metals; Heat treatment
Surface hardening of steel by carbon and nitrogen absorption through heat treating at a specific temperature while in contact with cyanide salt, and following with quenching.
hardness
Metals; Heat treatment
The ability of a metal to resist penetration. The principle methods of determining hardness of steel are the Rockwell, Brinell and Scleroscope Tests.
microhardness
Metals; Heat treatment
The hardness of a material as determined by forcing an indenter into the surface of the material under a very light load, with the indentations so light that they must be measured under a microscope.
heat treatment
Metals; Heat treatment
The heating and cooling of metals or alloys in the solid state for the purpose of obtaining certain desirable conditions or properties.
austenite
Metals; Heat treatment
The solid solution of iron and carbon achieved by heating to high temperatures above the upper critical temperature. Known as the austenitizing temperature, this temperature must be attained to ...
martempering
Metals; Heat treatment
A hardening method for steel involving quenching from the austenitizing temperature into some heat extracting medium, usually salt, which is maintained at some constant temperature above the point at ...
marquenching
Metals; Heat treatment
A hardening method for steel involving quenching from the austenitizing temperature into some heat extracting medium, usually salt, which is maintained at some constant temperature above the point at ...
