annealing Slow heating and cooling of a metal, alloy or glass to relieve internal stresses and make up dislocations or vacancies introduced during mechanical shaping, such as rolling or extruding (ejection). Annealing increases the material's workability and durability. Tempering, on the other hand, is a process that involves rapid cooling.
