| 摘 要： | 本文计算了孪晶马氏体基体和孪生部份的应变张量,发现二者的切变分量大致相反,故应变能降低。马氏体片可依靠基体和孪晶间的自协作效应沿孪晶面的法问长大。根据对不同惯习面法线的位移矢量的分析,{10,3,15}f面可构成宏观的不变惯习面,而{575}f,{252}f和{111}f面则难以构成。

| Abstract: | The shear components of strain tensors for matrix and twin crystal of
twinned martensite were opposite roughly after calculation, and the strain energy
would be reduced. The growth of martensitic plates along the normal direction of
the twin plane may depend upon the effect of self-accommodation between the ma-
trix and twin crystals. Based upon the analysis on the displacement vectors of the
normals for different habit planes, the {10,3,15}_f plane could make up the macro-
scopic invariant habit planes; but the (575)_f, (252)_f, (111)_f planes are difficult to
become the invariant planes. |
