摘要(Abstract)：

采用光学显微镜、扫描电镜、拉伸测试、杯突实验和耐蚀实验等分析了不同Cu含量对Cr21铁素体不锈钢的组织、力学性能、成形性能和耐蚀性能的影响。结果表明,含0.36%Cu的Cr21铁素体不锈钢晶粒大小均匀,屈强比最小,伸长率达到35.7%,塑性应变比达到最大值为1.82,杯突IE值达到8.51,γ纤维织构{111}<112>的强度最高达23.1,具有最佳的力学性能和成形性能。当Cu含量超过0.36%时,{111}<112>织构强度出现明显下降的趋势,而{112}<110>和{001}<110>织构强度增加。当Cu含量超过1.08%时,Cr21铁素体不锈钢的点蚀电位增加明显,耐蚀性能随实验钢中固溶的Cu含量的增加而增大。
