从一系列实验和理论结果的考虑,A型和B型的Fe的状态杂化用18级杂阶的形式组成。每级杂阶有不同的共价电子、原子磁矩和单键距等参数,根据这些参数和由N的双原子分子N_2光谱所及的单键距,α-Fe,γ-Fe和Fe_4N=Fe~cNEe_3~f的价电子和磁矩结构进行了分折。从所得结构,从中子衍射所得的α-Fe晶格空间的磁矩分布和α-Fe的[00],[111],[110]实验曲线得到理解。Fe~cNFe_3~f中Fe~c和Fe~f的差别找到了原因。α-Fe→γ-Fe~f是因为磁结构的来源曾谨慎加以考虑。高温氮化的来源均已追溯到共价电子结构的根源。

On the consideration of series of experimental and theoretical results, the type A and B hybridizations of states of Fe are constructed in the form of 18 discontinuous of hybride levels, belonging to which various valence electrons, atomic magnetic moment and bond length parameters are listed. 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.
