| 摘 要： | 对１Ｃｒ１８ｎｉ９Ｔｉ钢制生理盐水的消毒锅炉在使用使用过程中产生的裂纹与扩展的特征、裂纹源区及裂纹尖端断裂面及母材的化学成分等进行分析，断定此裂纹是点蚀造成应力集中后形成裂纹源并扩展产生的应力腐蚀裂纹。

| Abstract: | Experiments have been done to find out the causes of cracking of the steel 1Cr18Ni9Ti.Through study on microstructure,the emerging of cracks and its propagation,and analysis on chemical content of the original area,the peak area,cracking area,and the base material of the cracking,it can be drawn that the cracking was caused by the propagation of a cracking source,which was resulted from pitting. |
