摘要
对 10 16× 2 1mm弯管裂纹情况进行了调查研究 ,用金相显微镜和扫描电镜对裂纹形态及特征进行了观察和分析 ,发现裂纹表面及周围晶界有铜相存在。进一步分析 ,认为外来铜污染是引起弯管开裂的主要原因。
An investigation was made into the crack in the 1016×21mm bent pipe.An observation and analysis of the appearance and features of the crack by using metallographic microscope and scanning electron microanalyzer showed copper structure on the surface of the crack and its grain boundary.Further analysis indicated that external copper pollution was the major cause of the crack in the bent pipe.
