经常观察到相邻多晶粒中的马氏体显微结构是相关的。例如，Arlt的显微照片（J Mat Sci 22：2655-2666，1990）[1]（其中一张复制于（Bhattacharya，Microstructure of Martinate，2003）[10，p 225]）显示了在（{}）中的马氏体-到-四马氏体相变中层状结构跨越晶界的扩展。 ext{BaTiO}}_{3}）。这种观察结果与晶界处变形的相容性要求有关。使用推广的阿达玛跳跃条件，这是探讨在马氏体相变的非线性弹性模型的情况下，双晶体与适当取向的柱状几何形状，其中在两个晶粒的微观结构被假定为只涉及两个马氏体变体，与平面或非平面的晶粒之间的界面。
It is often observed that martensitic microstructures in adjacent polycrystal grains are related. For example, micrographs of Arlt (J Mat Sci 22:2655–2666, 1990) [1] (one reproduced in (Bhattacharya, Microstructure of martensite, 2003) [10, p 225]) exhibit propagation of layered structures across grain boundaries in the cubic-to-tetragonal phase transformation in ( { ext{BaTiO}}_{3} ). Such observations are related to requirements of compatibility of the deformation at the grain boundary. Using a generalization of the Hadamard jump condition, this is explored in the nonlinear elasticity model of martensitic transformations for the case of a bicrystal with suitably oriented columnar geometry, in which the microstructure in both grains is assumed to involve just two martensitic variants, with a planar or non-planar interface between the grains.
