Abstract The valence electron structure ofε-Fe_3C was studied on the basis of recently published Yu’s“empirical electron theory of solids and molecules”and corresponding known crystallographic data. It seems that the discussion about both the analysis of the bond length differences and the magnetic moment of atoms may warrant such conclusions:(1)The Fe and C atoms inε-Fe_3C are of step A-11 and 6 respectively;(2)There exist n_(A(Fe-C))bond and n_A=0.8440;(3)The space distribution of n_A bonds forms regularly a 3-dimension network structure. It is estimated that this is the structure of higher mechanical strength and low-temperature stability;(4)Although the mechanical strength and hardness ofε-Fe_3C may be inferior to that of cementite Fe_3C, yet the former will be not so brittle as the latter owing to their more regular space distribution of n_A bonds.
