摘要
本文应用光学金相显微术研究了Fe-Cr-W-V-C合金中{225}_f马氏体的形核位置。观察确定,除奥氏体的晶粒界是马氏体的形核位置以外,奥氏体的孪晶界和亚晶界也是马氏体的优先形核的位置。估计了马氏体的惯习面。
This investigation, using optical metallographic microscopy, deals with the nucleation sites of {225}, artensite in a Fe-Cr-W-V-C alloy. The observation results indicated that twin boundaries and subgrain boundaries are also the preferential site of martensite nucleation in addition to austenite grain boun-daries. The habit plane of martensite was estimated.
