摘要
根据６０年前陆学善发现的Ａｌ－Ｃｒ合金相和郑建宣首次测定的Ａｌ５Ｃｏ２晶体结构，对近来发现的一些铝与过渡金属间的六角和正交相中的二十面体连接和二十面体结构块进行了简要的讨论．这些合金相都是准晶的近似晶体相．
Based on the intermetallic phases in Al-Cr alloys found by S.S. Lu and the crystal structure of Al_5Co_2 first determined by C.S.Cheng published 60 years ago,the interconnections of icosahedra and the icosahedral blocks in a number of hexagonal and orthorhombic phases in alloys of Al-transitional metals discovered recently are briefly discussed.Structurally these intermetallic phases are crystalline approximants of quasicrystals.
