Quick Summary

Full annealing is a heat treatment process for metals and alloys. It involves heating the material to a specific temperature, holding it there for a period, and then cooling it slowly to room temperature. This process is primarily used to improve the metal's ductility and reduce its brittleness, making it more workable for subsequent manufacturing steps, such as in the machine-tool industry. Full annealing can also help relieve internal stresses within the metal. The temperatures and times used vary depending on the specific metal or alloy and the desired properties, but they must remain within a range that prevents excessive crystal growth.1
