Abstract: The external magnetic field will change the phase transformation process from austenite to martensite, and influence the microstructure of martensite due to the magnetic difference of these phases. In this paper, the effect of high magnetic field on martensitic transformation is discussed. Related research shows show that magnetic field can increase the starting temperature of martensite transformation, which is mainly caused by the effects of magnetostatic energy, high field susceptibility and magnetostriction of magnetic field. The magnetic field boosts the transformation of martensite by promoting its nucleation and growth. However, the magnetic field has little effect on the morphology of martensite. At the same time, the latest progress and future prospects of martensite transformation under high magnetic field are introduced.
