| 摘 要： | 通过拉伸测试、冲击测试、硬度测试、透射电镜及扫描电镜观察分析等手段研究了不同热处理状态下2Cr16Ni2MoN不锈钢的组织与性能.研究结果表明,钢采用低于1000℃的固溶温度,组织中存在未溶的(Cr,Mo)23C6,当固溶温度高于1100℃时,马氏体板条明显粗化,均对钢的力学性能不利,钢比较适宜的固溶温度为1040℃.该钢时效硬化的主要原因是组织中析出与基体共格的(Cr,Fe,Mo)2C碳化物.钢经1040℃固溶,560℃时效可以获得较好的强度与韧性配合.

| Abstract: | The effect of heat treatment on microstructure and mechanical properties of aged hardening stainless steel 2Cr16Ni2MoN were examined by means of tensile test,impact test,hardness test,transmission electron microscope and scanning electron microscope.The results show that there are undissolved(Cr,Mo)23C6 carbides in steel when the lower solution treated temperature is used.Increasing the solution treated temperature results in coarsening of the packet and block structure of the lath martensite.The optimum so... |
