研究了Fe-27Mn-3.5Si合金冷轧诱导的马氏体择优取向。由于扁轧本质上是一种平面应变状态，因此采用冷轧诱导马氏体。该合金由层错和热马氏体组成，并在y基体中有一定的变异。通过冷轧，马氏体板优选地诱导为单一变体，从而产生优选的取向。观察到轧制诱导的e -马氏体具有（1013）e [3032]e的优选取向。结果表明，当c/a接近（8/3）1/2时，在y→e剪切变形中，[3032]e和（1013）e法向分别收缩和膨胀最大。
Preferred orientation of e martensite induced by cold rolling is studied in an Fe-27Mn-3.5Si alloy. Since the flat rolling is essentially a plane strain condition, cold rolling is applied to induced the martensite. The alloy consists of stacking faults and thermal e martensite with some variants in y matrix. By cold rolling, e martensite plates are preferably induced with a single variant, producing a preferred orientation. Rolling-induced e martensite is observed to possess a preferred orientation of (1013)e [3032]e. It is revealed that the [3032]e and normal direction of (1013)e experience the largest contraction and expansion, respectively, in y → E shear deformation when c/a is almost (8/3) 1/2 .
