Define heat treatment processes and their types

Question

Accepted Answer

Heat treatment processes are used to alter the physical and mechanical properties of materials through heating and cooling.

Heat treatment processes involve heating and cooling of materials to alter their properties
Types of heat treatment processes include annealing, quenching, tempering, and normalizing
Annealing involves heating the material to a specific temperature and then cooling it slowly to make it softer and more ductile
Quenching involves cooling the material rapidly to increase its hardness
Tempering involves heating the material to a specific temperature and then cooling it slowly to increase its toughness
Normalizing involves heating the material to a specific temperature and then cooling it in still air to make it more ductile and reduce internal stresses
