Precipitation Hardening

Increased hardness of metal due to precipitation of alloy elements.

This treatments is obtained by heating an alloy to a temperatures between the ambient and the solubilization one, this allows to the alloy elements to precipitate in the crystal grain of the metal and increase its hardness.

The level of precipitation is determined by both the process temperature and its duration, it is preferable to perform a longer treatment with lower temperatures than using high temperatures for a short time.

Common usages

This treatment increases the hardness of metal due to the precipitation of alloy elements inside the crystal grain of metal.
