摘要
本文采用显微组织、成分分析和断口分析等方法对液化气贮罐在使用中产生裂纹的类型和原因进行了综合分析 ,说明裂纹是腐蚀应变疲劳作用的结果。
The type and the cause of the cracks found during the service of a LPG vessel were analyzed comprehensively by means of chemical and structural analyses as well as fractography.It has been concluded that the occurrence of the cracks is a result of corrosion strain fatigue.
