2) prior austenite grain size
原始奥氏体晶粒
5) γ grain boundary
奥氏体晶界
1.
The research show that the second phase particles have strong pinning force to γ grain boundary of CGHAZ in micro-calcium steel.
结果表明,弥散分布的含钙的氧化物粒子,钉扎了焊接热循环过程中CGHAZ的奥氏体晶界迁移,限制了奥氏体晶粒的长大,获得较细的焊接CGHAZ晶粒度,进而改善了微钙钢焊接CGHAZ的强韧度。
6) The grain boundary of austenite under cast condition
铸态奥氏体晶界
