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-M n-C alloys with the supplemental tests on Fe-Ni-C and Fe-Ni-Co-Ti allo ys. 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 in duced by ultra high magnetic field for Fe-Ni-C and Fe-Ni-Co-Ti alloys.
