摘要
本文在文献基础上,运用金相,电化学方法研究了50Mn18Cr4电机护环钢依照QHJ-79试验标准在硝酸盐介质中应力腐蚀开裂(即SCC)的性质.结果指出,此体系中SCC的控制过程为阳极溶解.
On the basis of the first reference,the properties of SCC has been investigated for 50Mn18Cr4 steel in the nitrate solution according to QHJ—79 test standard by metallographic microscope and electrochemistry method. The results show that anodic dissolution is the control process for the SCC in the system
