摘要
利用干涉显微镜首次测得了板条马氏体形状应变的大小及方向。试验测得惯习面为（５７５）_ｆ的标准变体有两个形状变形方向；板条马氏体形状应变值小于Ｓａｎｄｖｉｋ和Ｗａｙｍａｎ的估计，证实了切－转晶体学理论预测是正确的。
The magnitude and direction of lath martensitic shape strain is firstly measured by a new interference method in this research. The results obtained show that the same habit variant (575)f has two shape strain directions, and measured magnitude of the shape strain is smaller than the one deliberated by Sandivk and Wayman. All experimental data support forecasting of shear-rotation crystallography theory.
