%X The valence electron structure of martensite in Fe-Co-Cr based high-alloy steel is calculated using the em-pirical electron theory of solids and molecules (EET). The results show that the incorporation of cobalt leads to a rise in nA from 0.3835 to 0.4684, which enhances the bonding forces between atoms in a-Fe matrix. Meanwhile, the incorporation of Co changes the valence electron structure of segregated structure units formed by C and other alloying elements, and increases nA for the segregated units containing C-Me sig-nificantly, resulting in changing the precipitation behavior of the secondary phases during tempering and strengtheningthe resistance to tempering.
