摘　　要：利用固体与分子经验电子理论(EET),计算23MnNiMoCr54钢中温回火组织特征相的电子结构参数。根据固溶强化作用因子和界面强化系数的计算结果,从电子层次研究了Mo强化23MnNiMoCr54钢的微观机理。结果表明:对于23MnNiMoCr54钢中温回火组织,Mo主要强化了α-Fe-C结构单元,对界面强度影响不大。Electron structure parameters of 23MnNiMoCr54 in medium temperature tempered state were calculated by employing empirical electron theory of solids and molecules （EET）. Based on the calculating results of solid solution strengthening gene and interface strengthening coefficient, the strengthening mechanism of Mo on 23MnNiMoCr54 steel was investigated. The calculating results show that the main effect of Mo is to strengthen ot-Fe-C unit in tempered mierostructure and almost no contributions to interface strength.
