Kinetic characteristics of martensitic $\gamma \rightarrow \alpha$-transformation in iron alloys are explained based on both the results of a study of austenite magnetic properties and the influence of strong magnetic fields on the displacement of the martensitic point in Fe—Ni and Fe—Ni—Mn alloys. As shown, the changing of the transformation nature can be explained by the change of the structural phase transformation (isothermal kinetics) on the first-kind magnetic phase transition (athermal kinetics).
Key words: martensite, austenite, magnetic field, magnetostriction of paraprocess, spontaneous magnetostriction, structural transformation, magnetic transition, hysteresis.
