Annealing
Annealing is a technical term in foundry techniques and it refers to heat treatment of cast products with the goal to achieve higher toughness of a material. The process of annealing consists of two procedures: hardening and tempering.
Hardening is done with iron alloys with steel and quenching and tempering is done through heating and cooling to ambient temperature.
According to the variety of the agents which are used for quenching we differentiate between water quenching, air quenching and oil quenching.
In the case of steel through hardening martensite is created, which is transferred through a tempering procedure to carbide with a fine dispersion within the material.
