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.
