| 摘 要： | 利用固体与分子经验电子理论对常用低合金耐热钢的价电子结构进行了计算。结果表明,在α-Fe基体中加入适量的合金元素和C,可提高结构单元的共价电子数nα和键能Eα,强化了基体。利用结构单元中nA与EA最强的两个结构单元作为评价常用低合金耐热钢使用温度的价电子结构参数,可在一定程度上定性地说明常用低合金耐热钢使用温度的不同。

| Abstract: | The valence electron structure parameters of low alloy heat-resistant steel in common use were analyzed on the basis of the empirical electronic theory(EET) of solids and molecules.The results show that the covalent electron number and bond energy in structure cells can be improved by adding proper alloy elements and carbon in α-Fe matrix,thus the matrix can be strengthened.The covalent electron numbers and bond energies of the two stronger structure cells were selected as valence electron structure parameters to evaluate service temperature of low alloy heat-resistant steel in common use,which can explain the different service temperature of low alloy heat-resistant steel in common use. |
