摘要
本文是关于铝基多元系准晶合金形成规律的研究．在研究中采用了著者提出的加和原则对多元系铝基准晶的形成规律进行了解析．结果表明，某些准晶态合金可以按一定成分范围相互加和，通过快速凝固和普通熔铸等方法制备新的多元系准晶合金，同样根据准晶的加和原则，可以从某些多元系准晶预测新的基本准晶．
This paper isa theoretical study about the constitution of Al-base multicomponent qua-sicrystalline alloys. The authors suggest a quasicrystalline alloys compositional additivityprinciple，present the Al-base multicomponent quasicrystalline alloys constitution and forma-tion characteristics，and analvze these results. The study results show that，new multicom-position quasicrystals can be constituted by adding some basic quasicrystals in some composi-tion scope；these new quasicrystals will be obtained by means of rapid solidification or ingotmetallurgy，and the quasicrystals additivity principle can be useful in predicting basic qua-sicrystals on the base of known multicomponent quasicrystals.
