Effect of magnetic field on martensitic transformation in some ferrous alloys

Abstract

Magnetic field is one of external fields affecting martensitic transformations. In this paper, we review the change in transformation temperature and morphology by the application of magnetic field in some ferrous alloys with different magnetic properties, and explain their behavior thermodynamically. Besides, the magnetic field-induced strain in some ferromagnetic shape memory alloys is presented briefly. Moreover, kinetics of both isothermal and athermal martensitic transformations is explained based on a phenomenological theory.
