对1J30升温和降温过程分析得出,深低温条件下1J30的马氏体转变为不可逆转变。同时,对1J30内马氏体衍射斑点分析得出:有许多平行的极薄的马氏体片生成;马氏体与奥氏体的位相关系符合“西山关系”。对软磁材料中的马氏体研究具有一定的意义。
1J30 temperature cooling process analysis showed that 1J30 martensitic transformation into irreversible transformation. At the same time, the analysis of 1J30 martensite diffraction spot shows that there are many parallel ultrathin martensite sheets, and the phase relationship between martensite and austenite is in accordance with the relationship between Xishan and Xishan. Martensitic materials in soft magnetic research has a certain significance.
