EXAMINATION OF SENSITIZATION OF AUSTENITIC STAINLESS STEELS BY DOUBLE-LOOP EPR TEST METHOD
双回路EPR法测定奥氏体不锈钢的敏化

Sensitization of austenitic stainless steels, which were traditionally examined by solution and heat treatments, are measured by double-lmp EPR test methcd . ?he C type TE curves of various samples are obtained , and then canpared with the curves established by the Rocha and Cihal. The results indicate that the EPR technique can detect lcnv degrees of sensitization and can be performed quickly. The areas of sensitization detemined by the prosend methcd are latger than that by Rocha and Cihal's curves.
