Abstract
Effects of ultra high magnetic field of both pulse and steady types on martensitic transformation have been studied, using Fe-Ni-Mn, Fe-Ni-Mn-C alloys with the supplemental tests on Fe-Ni-C and Fe-Ni-Co-Ti alloys. It is found that the martensitic transformation is induced at room temperature not only athermally but also isothermally either by pulse magnetic field or by steady magnetic field for Fe-Ni-Mn and Fe-Ni-Mn-C alloys. This fact is in sharp contrast with that no martensite is induced by ultra high magnetic field for Fe-Ni-C and Fe-Ni-Co-Ti alloys.
