合金的辐照肿胀与价电子结构的关系

Relationship Between Irradiation Swelling Behaviour of Alloys and Their Valence Electron Structure

根据经验电子理论对价电子结构的计算结果，研究了合金的价电子结构与其辐照肿胀行为的关系。以价电子结构的不同，解释了３种首选合金在辐照肿胀行为上的差别，并阐明了不锈钢及镍基合金中含镍量和辐照肿胀抗力的内在联系。据价电子结构分析认为，金属间化合物是很有潜力的抗辐照肿胀结构材料。

The relationship between the valence electron structure of alloys and their irradiation swelling behaviour is investigated,on basis of results of their valence electron structure calculated by means of the empirical electron theory.The difference of the irradiation swelling behaviour among three prior candidate alloys is explained by their different valence electron structure.The intrinsic relation between nickel amount of alloys,including austenitic stainless steels and nickel alloys,and their irradiation swelling behaviour is clarified.From the viewpoint of valence electron structure,intermetallic compounds are potential structural materials with excellent resistance to irradiation swelling.
