摘要
通过对铁基粘结相变体向量关系等进行分析,在平面金相照片上同一晶粒内选取数个互不平行的马氏体变体迹线,利用不同变体的迹线间夹角测定了孪晶面指数。结果表明,此法克服了TEM透射电镜等测定界面共格关系的困难,收到了事半功倍的效果。
With the analysis of Fe-base binder phase’s variable vector relation, it’s demonstrated that twin plane indices can be measured by angles among different martensite variable traces which are chosen in same crystalline grain but mutually-nonparallel by right of planar metallographic photo. The results indicated that this way is better than TEM method in measurement of martensite habit plane..
