摘要/Abstract

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。

关键词: 板条马氏体, 形状应变, 相变晶体学

Abstract: 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.

Key words: lath martensite, shape strain, martensitic transformation crystallography
