采用SEM、TEM及微拉伸试验等方法,对深冷轧制变形90％的AISI310S奥氏体不锈钢不同温度(500 ～1000℃)及时间(2～60 min)退火处理后的微观组织及性能进行了研究.结果表明:当退火温度在700℃以下时,深冷变形组织处于回复阶段;退火温度在700℃以上时,深冷变形组织处于再结晶阶段,随着退火温度升高至1000℃,再结晶程度充分完全的同时伴随着再结晶晶粒的长大,1000℃退火10 min条件下,奥氏体晶粒长大至3μm左右.在退火温度800℃下,随着退火时间从2 min增加到60 min,奥氏体不锈钢晶粒尺寸从300 nm增大至750 nm.退火温度从500℃增至1000℃,奥氏体不锈钢的强度和硬度呈现出先升高后下降的趋势,伸长率则一直呈增加趋势,断口形貌也由韧、脆性混合断裂向韧性断裂发生转变.
