age hardening

age hardening
a process of increasing the hardness and strength by the precipitation of particles of a phase from a supersaturated solid solution alloy. The hardening cycle usually consists of heating or annealing at a temperature sufficiently high to maintain solid solution, rapid cooling or quenching to retain the supper saturated solid solution, and subsequent heating at a temperature lower than the solution anneal to effect the precipitation.
