Alloysoften is a term used in some materials science and engineering writings to refer to processes or effects that reduce the hardness or strength of an alloy in order to increase its ductility or formability. The term is not standardized; different authors may use it to describe distinct heat-treatment sequences or thermomechanical processes, and it may be encountered in patent disclosures, industry manuals, or academic discussions without a single agreed definition.

Softening can arise from recovery, recrystallization, grain growth, dissolution or coarsening of strengthening precipitates, or relief

Typical approaches associated with alloysoften include full annealing of carbon steels, solution treatment of aluminum alloys

Industries such as automotive, aerospace, packaging, and consumer electronics may employ alloysoftening steps to improve formability

Related processes include annealing, tempering, and recrystallization, as well as work hardening and stress relief.
