Abstract��It��s found that martensite transformation in 1J30 is irreversible by analyzing the heating and cooling process of 1J30. Through TEM analysis, the following conclusions were made: There had twins in martensite; the crystallographic orientation between martensite and austenite conformed to Nishiyama relationship; In diffraction photographs, there had high��order diffraction spots, proving the martensite films were very thin, which were very important for martensite research in soft magnetic materials.
