在介绍固体与分子经验电子理论（EET理论）和扩展的EET理论的基本原理和方法的基础上，综述了这一理论在钢铁材料成分设计、组织结构转变和性能预测方面的应用及其研究现状；归纳了在晶体价电子结构理论角度上探讨不锈钢中合金元素的作用及不锈钢抗腐蚀机理的研究进展；并提出了采用扩展的EET理论，从合金元素对晶体价电子结构影响的层次上揭示不锈钢抗腐蚀性能的本质以及发展新型不锈钢的计算合金设计新方法。
Based on a brief introduction of EET and the basic principles and methods of the theory of extensions of EET , the applications of solids and molecules empirical electron theory (EET theory) on the design of steel material composi-tion,structure’s transition,forecasting of properties and research status is summarized. It sums up the research progress of the effects of alloying elements in stainless and the anti-corrosion mechanism of stainless steel from the view of the crystal structure of the valence electrons. Also,it propose that by using the theory ,it can reveal the nature of the corro-sion resistance of stainless steel and develop the new methods of the new stainless steel’s calculation of alloy design from the level of the influence of alloying elements on the price electronic’s structure in crystal.
