annealing

annealing (ənēl´Ĭng), process in which glass, metals, and other materials are treated to render them less brittle and more workable. Annealing consists of heating the material and then cooling it very slowly and uniformly; the time and temperatures required in the process are set according to the properties desired. Annealing increases ductility and lessens the possibility of a failure by relieving internal strains. The process, also called hot working, was known to the ancients.

annealing

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.
