用余氏EET理论计算奥氏体中的C-Me偏聚结构单元的价电子结构,提出了固溶体中C-Me偏聚结构单元权重的计算方法,建立了低合金锰钢、铬钢奥氏体中C-Me偏聚结构单元的相结构因子n_A及其权重W与C-曲线鼻子温度T_P,T_B,C-Me偏聚结构单元的相结构因子F_C~D及其权重W与C-曲线最短孕育期t之间的关系式,并用这些关系式计算出了铬锰低合金结构钢的C-曲线鼻子温度T_P,T_B和最短孕育期t,计算结果与实测值吻合,表明此种方法可用于其他低合金钢的C-曲线特性点预测。
The calculation of the valence electron structure of the C-Me segregation unit in austenite by using the Yu’s EET theory and the calculation of the weight of the C-Me segregation unit in the solid solution are presented. The low alloy manganese steel, The phase structure factor n_A and its weight of C-Me segregated structural unit in body and the phase structure factor F_C ~ D of segregated structural unit T_P, T_B and C-Me of C- The shortest incubation period t, and using these relationships to calculate the C-curve nose temperature T_P, T_B and the shortest incubation period t of chromium-manganese low-alloy structural steel, the calculated results are consistent with the measured values, indicating that this method is available Prediction of C-curve characteristics of other low-alloy steels.
