摘要(Abstract)：

采用TEM、SEM等研究13Cr超级马氏体不锈钢不同热处理后的的显微组织。结果表明,试验用钢淬火后的组织为板条马氏体。800、850、900、950、1000、1050和1100℃淬火后试样原始奥氏体晶粒尺寸为16.8～56.88μm;随淬火温度的升高原始奥氏体晶粒逐渐长大,马氏体板条束逐渐粗大。不同温度淬火650℃回火,A钢和B钢的组织均为保留原马氏体位相的细小回火马氏体。试样在1050℃淬火并在不同温度回火后有逆变奥氏体产生,在650℃以下回火时随着回火温度的升高和保温时间的延长逆变奥氏体含量逐渐增多,且回火后逆变奥氏体主要以长条状及菱形状分布于马氏体板条束间及奥氏体晶界处。
