摘　　要：本文研究了按成分加和原理快冷制备多元准晶AlCuFeMg等形成条件研究表明除部分多元系准晶合金可直接按成分加和原理制备外,大多数由此法制备的多元合金要经过热处理后才能形成准晶.800℃是重要形成准晶的热处理温度.This paper have investigated the formation condition of AlCuFeMg etc. which prepared by the rapid solidification powder making technigue according to the composition-adding rule. The study shows that except a part of alloys, for which the quasicrystalline may be formed dirctly, the majority of the alloys must be heated for forming quasi crystalline. The temperature 800鈩?is an important condition forming quasicrystalline.
