本文研究了热处理对310S奥氏体不锈钢的微观结构和组织的影响。对样品材料进行冷轧,使其厚度分别减少20%、50%和90%,然后在1023、1223和1323 K下退火5、15和30 m.n。在厚度减少20%后,奥氏体内产生孪晶,且可观察到形变诱发的α’马氏体,孪晶的体积分数大于α’马氏体。当厚度变化由50%增加到90%,α’马氏体的体积分数由11%增加到69%,孪晶被α’马氏体取代。发生形变后奥氏体相主要为Bra.s、Goss和S织构,α’马氏体的主要纹理为R-Cu、R-cube、F和E组份。随着形变量增大,Bra.s织构增加,Goss织构减少。退火过程中,马氏体向奥氏体转变,并发生了再结晶,使Goss和Bra.s再结晶织构的体积分数增加。材料退火后的结构与冷轧后的大致相同。1223 K下退火5 m.n的马氏体转变速度明显高于1023 K下的。在1023 K下退火5 m.n,由于马氏体不完全转变和初级再结晶,未能检测到等轴组织。获得超细晶粒组织的最佳退火温度为1023 K,退火时间为15 m.n。在1173 K和1273 K时出现快速再结晶和晶粒生长。
