摘要
应用光学显微术及透射电子显微术和B-M表象晶体学理论对60和60Si2Mn钢中马氏体的形态、亚结构与晶体学特征进行了研究。中碳铁基马氏体的平均惯习面为{225}_f。铁基马氏体的微观惯习面为{111}_f。实测惯习面、取向关系及切变方向等与利用Bain应变及(100)[011]_f点阵不变切变系按B-M理论计算的结果一致。
The morphology, subtructure and crystallography of martensite insteels 60 and 60Si2Mn have been Studied by means of optical and transmission elec-tron microscopy combined with B-M phenomenological crystallographic theory. Theaverage habit plane of martensite in medium carbon iron alloy is {225}_f. Experi-mental observations on habit plane and O-R are in agreement with the B-M theoryby using the Bain strain and lattice invariant shear on (100) [011]_f.
