Orientations of type II twin boundaries in B2→B19′ martensitic transformation in dynamic theory

详细

The paper analyzes the possibility of describing the orientations of type II twin boundaries in B2→B19′ martensitic transformation in the framework of dynamic theory based on the concepts of heterogeneous nucleation and wave growth of martensite crystals. It is shown that the twin boundary orientations can be defined by strain fields in crystal contact regions characteristic of self-accommodated groups with common 〈001〉_B2 poles.
