The martensitic transformation (MT) under tensile deformation at 77K in a series of Fe-Ni-Mn alloys was studied. The amount of maitensite formed during the tensile test depends on the applied stress and on the Mn content which determines the martensitic point and the MT start stress. Elongation of the tensile tested samples has a maximum value in the alloys containing the 50% amount of martensite formed during the tensile test. Parameters which determine the intensity of the MT and plasticity of the samples under loading are discussed.
