一、Fe-C、Fe-C-Cr奥氏体的价电子结构 按文献[1,2],本文建立了含0.15—2％C的Fe-C奥氏体的价电子结构,见表1。依文献[3],Cr在Fe-C奥氏体中应呈C-Cr偏聚状态,根据文献[3,4]的方法,本文又建立了Fe-C-Cr奥氏体的价电子结构。为了说明符号n~D的意义,文中给出了含0.3％C-Cr晶胞的价电子结构(见表2),其余Fe-C-Cr奥氏体的价电子结构见表1。作者认为表2中C与Fe~f、 First, the valence electron structure of Fe-C, Fe-C-Cr austenite According to the literature [1,2], the valence electron structure of Fe-C austenite containing 0.15-2% C was established in this paper, . According to the literature [3], Cr should be in the Fe-C austenite C-Cr segregation state, according to the method of literature [3,4], this paper also established the valence electron structure of Fe-C-Cr austenite . In order to illustrate the significance of symbols n ~ D, the valence electron structure of 0.3% C-Cr unit cell is given in the paper (see Table 2). The valence electron structures of the remaining Fe-C-Cr austenite are shown in Table 1. The authors believe that Table 2, C and Fe ~ f,
