What is Heat Treatment ?

Question

Accepted Answer

Heat treatment is a process used to alter the physical and mechanical properties of materials through heating and cooling.

Heat treatment involves heating a material to a specific temperature and holding it at that temperature for a certain period of time.
Different heat treatment techniques, such as annealing, quenching, tempering, and case hardening, are used to achieve desired properties.
Annealing is used to soften materials and relieve internal stresses, while quenching is used to harden materials by rapid cooling.
Tempering is a process of reheating quenched materials to reduce brittleness and increase toughness.
Case hardening involves adding a hard outer layer to a material while maintaining a softer core.
Heat treatment is commonly used in the manufacturing of steel, aluminum, and other metal alloys.
