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,发现了板条马氏体中同惯习面的不同变体,证实了切转晶体学理论的预测。
The magnitude (m 1) and direction (d 1) in the shape
strain of lath martensite were measured by an interference microscope. The results obtained
show that the average value of the magnitude is m 1=0 134 6 μm, and the standard variant
with (575) f as its habit plane has two shape strain directions which are close to 001 f and
110 f. The different variants which have the same habit plane were also found. All
experimental data support the prediction of the shear rotation theory.
