The microstructure observation in the microfissures suggests the liquation microcrack results from grain boundary liquation by constitutional liquation of MC carbides and formation of continuous and or semi-continuous low melting liquid films, however, th

液化裂纹起源于MC碳化物的组份液化而形成的晶界连续或半连续的低熔点共晶液化膜，固相裂纹形成的则是高能电子束流的快速瞬态热冲击效应的直接结果。
