Heat treating is a method used to modify the physical and sometimes chemical properties of a material, most commonly metals. The process typically involves heating the material to a predetermined temperature, maintaining that temperature for a set duration, and then cooling it swiftly. This sequence of actions alters the material's crystal structure and atomic arrangement, effectively changing its properties.
Key heat treating techniques include annealing, which softens the material to improve machinability by reducing hardness and brittleness, and quenching, which increases hardness through rapid cooling. Another process, tempering, involves a subsequent reheating of quenched material to reduce internal stresses and increase toughness. These processes collectively serve to enhance the material's mechanical performance and durability.
