Age hardening, also known as precipitation hardening, is a type of heat treatment that is used to impart strength to metals and their alloys. It is called precipitation hardening as it makes use of solid impurities or precipitates for the strengthening process. The metal is aged by either heating it or keeping it stored at lower temperatures so that precipitates are formed.
Advantages of Age Hardening
Some of the advantages that age hardening offers are listed below:
Imparts high tensile and yield strength to the metal
Enhances wear resistance
Age hardening facilitates easy machinability
Does not cause distortion to the part
