grain boundary carbide的意思|示意

This paper shows that inheritance phenomenon of coarse austenite grains are due to the boundary segregation of carbide along the prior austenite grain boundary.

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。

The authors suggest that the primary factors of the reheat embrittlement are precipitation of coarse carbide along the grain boundary and secondary hardening in the grain.

出现再热脆性的主要原因是晶界粗大碳化物的析出和晶内二次硬化。

The analysis show that the main reason to easy erode austenite grain boundary after tempering is the precipitation situation of carbide.

分析可知，碳化物的析出情况是回火后易侵蚀出奥氏体晶界的主要原因。
