摘　　要：基于奥氏体不锈钢马氏体磁性特征,用MP30E-S型铁素体测定仪定量测定马氏体相转变量。对两种常用304,316材料冷成形拉伸试件、波纹管、封头进行了形变马氏体检测试验研究。结果表明:随着工程应变量增加,形变诱发马氏体相的含量因而随之增加,316材料较304材料形变诱发马氏体相含量小得多,形变马氏体相变量的大小与材质、相对变形率有很大的关系。Based on the martensite magnetic characteristics of austenitic stainless steel,the deformation- induced martensite were tested by using the MP30E - S measurement instrument for the cold formed ten- sile pieces,bellows and heads made of two common 304,316 material respectively. The research shows that the amount of deformation - induced martensite have very great relation with the deformation and the materials, it increases immediately as the engineering deformation added, the deformation -induced mar- tensite of 316 material is more lesser than 304 material.
