AN ANALYSIS OF VALENCE ELECTRON STRUCTURE OF Fe-C-Mn ALLOYING AUSTENITE
Fe—C—Mn合金奥氏体的价电子结构分析

The valence electron structure of Fe-C-Mn alloying austenite containing 1.6% C(mass fraction) has been established by using bond length difference (BLD) method of the empirical electron theory of solids and molecules. The experimental results show that in unit cell containing C and Mn atoms, Fe~c, Fe~f and Mn atoms are on the 16th, 18th and 10th hybrid levels of B-type hybridization states respectively, and the carbon atom is on its 6th hybrid level. The simultaneous increase in C and Mn content will increase the number of the strongest C-Mn bond, thus lead to the increase in austenitic stability and work hardening capacity.
