Ⅰ. THE VALENCE ELECTRON STRUCTURES OF MARTENSITE IN LOW ALLOY ULTRAHIGH-STRENGTH STEELS AND THE SEGREGATION OF C-ME IN MARTENSITEThe valence electron structures ofmartensite in 30CrMnSiNi<sub>2</sub>A and Gc-4 steels can be established based on Refs. [1—3]. To be brief, only σ, n<sub>A</sub> and n<sub>c</sub><sup>D</sup> are listed in Table 1, which are the values of electron structures of martensite in 30CrMnSi<sub>2</sub>A and Gc-4 steels.
