Annealing Cold Worked Metals - Industrial Metallurgists

Cold-worked metals are recrystallization annealed for the purpose of reducing strength, increasing ductility, and obtaining a desired grain size. The changes in mechanical properties associated with recrystallization annealing are needed to enable further cold-working of metal stock such as sheet, plate, and wire that has been cold worked to its maximum limit or to meet
