On the basis of these parameters together with the parameters of N obtained from diatomic molecular spectroscopy, analysis of the valence electron and magnetic moment structures of α-Fe, γ-Fe and Fe_4N=Fe~cNFe_3~f are made. From these structures, interpretation of the space distribution of magnetic moments in the crystalline lattice of α-Fe obtained from neutron diffraction, and interpretation of experimental magnetization curves along [100], [111] and [110] of α-Fe are made and the cause of difference of the atomic magnetic moments of Fe~c and Fef in Fe~cN Fe_3~f are analysed. The phase transformation α-Fe→γ-Fe as due to magnetic origin is contemplated with care. The case hardening by nitriding steel at high temperature and the graphitation in cast iron due to heat effect at high temperature are both traced back to the valence electronic structure origin. 收稿日期: 1982-03-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 余瑞璜 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1982/V18/I3/336 1 余瑞璜(S.H.Yu),科学通报,23(1978) ,217． 2 Mattheiss, L.
