Tempering (metallurgy) - Wikipedia

Tempering is a heat treatment technique applied to ferrous alloys, such as steel or cast iron, to achieve greater toughness by decreasing the hardness of the alloy. The reduction in hardness is usually accompanied by an increase in ductility, thereby decreasing the brittleness of the metal. Tempering is usually performed after quenching, which is rapid cooling of the metal to put it in its ...

Jul 04, 2016 · Quenching is when you cool a solution treated steel quickly enough that carbides do not precipitate out of solution in a stable way. Tempering is when you take that quenched steel and heat it enough to begin precipitating the carbides but not enough to put everything back into solution. Quenched steels are brittle and tempering toughens them.

In tempering, a metal is reheated yet again, but now to a lower temperature than in annealing, normalizing, or quenching. Martensite is not a stable molecule in heat—it is achieved under shock—so tempering steel means destabilizing the martensite to let it start to convert to cementite and ferrite.
