用电化学方法研究了形变诱发马氏体对３０４不锈钢在活化状态下电化学行为的影响．结果表明，随着变形量的增加，马氏体转变量也增加，材料的电化学活性增大；通过测量各单相的电化学行为发现：马氏体的腐蚀电位比奥氏体的约负５５ｍＶ，这是形变诱发马氏体容易被选择性溶解的主要原因．
The effect of deformation-induced martensite on the electrochemical behavior of 304 stainless steel in activated state was studied by electrochemical method. The results show that with the increase of deformation, the amount of martensite transformation also increases and the electrochemical activity of the material increases. By measuring the electrochemical behavior of each single phase, it is found that the corrosion potential of martensite is lower than that of austenite 55mV, which is the main reason that deformation-induced martensite easily dissolves selectively.
