根据ＮｉＡｌ合金的三种Ｂ２→Ｌ１０（３Ｒ）马氏体相变表象理论模型，从原子迁动的晶体几何关系出发，讨论了Ｂ２→Ｌ１０（３Ｒ）马氏体相变晶体学及２４种马氏体变体间的位向关系。对分别由这三种相变机制形成的２４种马氏体变体之间的晶体学等价关系进行了详尽的说明
According to the theoretical model of three B2 → L10 (3R) martensitic transformations of NiAl alloy, the relationship between B2 → L10 (3R) martensitic transformation crystallinity and 24 kinds of horses The relationship between the orientation of the body variants. The crystal equivalence between the 24 types of martensite variants respectively formed by these three phase transition mechanisms is described in detail
