Ostrikov, E. Shmatok] Features of the shape of a macroscopic interplanar crack have been studied, and phenomena accompanying destruction in a monocrystalline ferromagnetic Ni2MnGa alloy with shape memory have been analyzed. It has been established that the initiation of destruction in Ni2MnGa is actively influenced by the processes of slip and interaction of twin boundaries in twin planes which are at small angles to each other, and also by the formation of Rose channels. On the source side of the surface at which the crack has nucleated, it is tooth-shaped. On this surface, there are signs of rotation of the crystal lattice from twins with boundaries parallel and perpendicular to the crack′s edges. The opening of the crack in its boundary regions leads to partial untwining.
