电子化合物晶体结构的新解释及其与Hume-Rothery经验规律的比较 Ⅲ.γ结构相电子化合物

A NEW EXPLAINATION ON THE CRYSTAL STRUCTURE OF THE ELECTRON COMPOUNDS AND ITS COMPARISONS WITH THE HUME-ROTHERY'S LAW Ⅲ.THE γ-BRASS TYPE ELECTRON COMPOUNDS

本文系统地综述了γ结构相电子化合物晶体结构的大量资料,发现Hume-Rothery经验规律在解释这一类含过渡金属的电子化合物晶体结构上所出现的局限性.文中引用合金晶体态电子浓度理论,对研究γ相电子化合物,尤其是含过渡金属的合金晶体结构,提出了一些新的看法.

After a systematic survey on numerous historical informations about the crystal structures of the γ-brass type electron compounds listed in foreign scientific literatures, this paper finds out a lot of confusions and contra-dications concerning the transition metals from the famous Hume-Rothery's Law.If the concept of the theory of the crystalline electron concentration for alloy proposed in the previous paper O3 is introduced, we can explain the structures clearly and clarify early disputable concept of the so-called Zero valence of the transition metals. Therefore, this paper should provide a new idea for a study of the Y type electron compounds especially for the γelectron compounds of transition metals.
