| 摘 要： | 通过热力学计算软件Thermo-Calc与相应的Ni基数据库,进行了耐热耐蚀合金Cr20Ni32A1Ti(％:0.10C、0.83Mn、0.56Si、＜0.005P、0.013S、20.89Cr、32.60Ni、0.26A1、0.39Ti、0.009 0N、0.076Cu)化学成分对主要析出相影响的研究,并分析了合金成分对合金初熔点和终熔点的影响.通过SEM、TEM和X射线能谱法对Cr20Ni32AlTi合金的组织和析出相成分进行了实验研究.结果表明,Cr20Ni32AlTi合金的主要析出相为M23C6和M(CN)碳化物,C含量(0.02％～0.10％)显著影响M23C6碳化物的析出量和开始析出温度；Cr含量(20％～22％)和C含量均影响合金的初熔点和终熔点.
