Abstract The shear components of strain tensors for matrix and twin crystal oftwinned martensite were opposite roughly after calculation, and the strain energywould be reduced. The growth of martensitic plates along the normal direction ofthe 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 thenormals 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 tobecome the invariant planes.
