基于固体与分子经验电子理论, 研究了316L不锈钢在模拟井下不同温度场中的价电子结构与其拉伸性能之间的关系。结果表明: 运用价电子理论计算得到的价电子结构参数σ、na′、Sc、Nl与动态拉伸试验的结果相吻合, 这些参数从微观层次揭示了在不同温度下, 316L不锈钢价电子结构与其力学性能之间的关系; 在讨论影响材料某一宏观力学行为的价电子结构参数时, 应将其看作一个相互影响的整体。

Based on the theory of empirical electron theory (EET) of solid and molecule, the relationship between valence electron structure and the mechanical properties of 316L stainless steel in a simulated underground temperature field was studied. The results show that the parameters σ, na′, Sc and Nl obtained by valence electron theory satisfied the results of the dynamical tensile test, and these parameters revealed the relationship between valence electron structure and the mechanical properties of 316L stainless steel at different temperatures in a micro-level. When the parameters which could impact the macroscopic mechanical behavior of a material were discussed, the various parameters should be regarded as a whole which affect each other.
