摘要：
Deformation of polycrystalline Ni-Mn-Ga alloys was studied for both the L21 parent phase and 10 M martensitic state. The effect of deformation by compression up to the fracture on mechanical behavior and structure change was studied for the inhomogeneous as-cast state and after annealing at 900○C for 50 hours. The structure, after deformation of the parent phase, observed by TEM reveals the presence of 10 M and 14 M martensite in the matrix, whereas the deformation of 10 M martensite does not show the change of the structure type. The stress-strain curves were analyzed and compared with the earlier published results.
