It can not interpret the fact why liquation cracks appear around the fusion line and are very short, but it may be satisfactorily explained by the high temperature strain distribution characteristic figure brought up by author.
传统观点尚不能解释液化裂纹出现于熔合线处和裂纹很短的现象,用作者给出的高温应变分布图可很好解释。
A large number of liquation cracks ar.
转子紫铜环熔焊焊接接头的失效原因分析认为:紫铜环熔焊焊缝内部存在大量的液化裂纹,其产生原因是焊缝内混入过量的氧元素,高温时形成低熔共晶体(Cu2O+Cu),低熔共晶体分布在晶界上,削弱了铜在高温时的晶间结合力,焊接接头力学试验结果表明存在焊接缺陷的HS201焊接接头抗拉强度显著下降。
It is observed that considerable liquation microcracks and some other microffissures called solid-state microcrack initiate in the regions nearby the fusion line and propagate across the grain boundary.
研究发现，熔合线附近的热影响区产生大量液化裂纹和沿晶扩展的固相裂纹。
