| 摘 要： | 研究了形变对奥氏体不锈钢在酸性氯离子溶液中阳极溶解的加速作用以及阳极溶解对力学行为的影响。形变使腐蚀电流密度显著增加,使阳极和阴极反应加速。阳极电流不但使恒载荷下的不锈钢蠕变速度增加,而且使屈服强度下降。形变的热激活理论分析表明蠕变速率的对数和阳极电流的对数成线性关系,屈服强度的倒数和阳极电流的对数成线性关系,这和实验结果符合得很好。

| Abstract: | The mutual influence between deformation and anodic dissolution of AISI 321 austenitic stainless steel in an acidic chloride solution was studied. The corrosion rate of the steel increased remarkably due to the deformation-accelerated anodic and cathodic processes. The creep rate was increased while the yield strength was reduced by anodic dissolution. The analysis by thermal activation theory of deformation showed a linear relationship between the logrithm of creep rate and the logrithm of anodic current. Besides, the reciprocal of yield strength was also linearly dependent on the logrithm of anodic current. These findings were in good agreement with experimental results. |
