Question

Accepted Answer

Heat treatment of metals involves processes like hardening, tumbling, and tempering. Various equipment and testing methods are used.

Processes involved in heat treatment: hardening, tumbling, and tempering
Equipment used: furnaces, quenching tanks, tempering ovens
Temperature settings for desired hardness quality vary depending on the metal
Testing methods for hardness: Rockwell hardness test, Brinell hardness test
Hardening operation involves heating the metal above its critical temperature and then rapidly cooling it
Tumbling operation is used to remove burrs and improve surface finish
Tempering operation involves reheating the hardened metal to a specific temperature to reduce brittleness
