研究表明，调质后粗晶奥氏体的遗传现象，是由于沿原奥氏体晶界碳化物偏聚析出的结果。
This paper shows that inheritance phenomenon of coarse austenite grains are due to the boundary segregation of carbide along the prior austenite grain boundary.
在试验的焊接条件下，WCX355超细晶钢在热影响粗晶区未有明显脆化，在回火区也未发生软化现象。
Under the experiment's welding condition, WCX355 ultrafine grained steels didn't distinctly embrittle in CGHAZ and didn't soften in tempering zone either.
