摘要
采用双回路电化学动电位再活化 (EPR)方法对经固溶处理和热处理后的奥氏体不锈钢进行了敏化测试 ,得到C型TTS图 ,并与根据化学测试方法建立的相应图对比 ,发现用双回路EPR方法测定奥氏体不锈钢的敏化更灵敏和准确 .
Sensitization of austenitic stainless steels, which were traditionally examined by solution and heat treatments, are measured by double\|loop EPR test method . The C type TTS curves of various samples are obtained , and then compared with the curves established by the Rocha and Cihal. The results indicate that the EPR technique can detect low degrees of sensitization and can be performed quickly. The areas of sensitization determined by the prosend method are larger than that by Rocha and Cihal′s curves.
