摘    要：著者提出了一项配制新型准晶系列的成分加和原则,根据这个原则配制合金,并且采用快速冷凝制得了Al-Cu-Fe-Mn,Al-Cu-Fe-Cr和Al-Cu-Fe-Cr-Mn系合金粉末。通过对所得合金粉末进行XRD,DTA,HXRD和TEM等仪器的测试结果表明,Al-Cu-Fe-Mn,Al-Cu-Fe-Cr和Al-Cu-Fe-Cr-Mn均为新的多元素准晶。文章还对三种准晶系的热稳定性及准晶相加热时相结构转变进行了研究。

Abstract: The authors thought that there probably exists a rule of composition addi-tivity in the constitution of quasicrystalline alloys, which means that some newquasicrytalline alloys can be constituted by the additivity of several quasicry-stalline alloy compositions. According to the rule, Al-Cu-Fe-Mn, Al-Cu-Fe-Crand Al-Cu-Fe-Cr-Mn alloy powders were produced by RS process. XRD, DTA,HXRD, TEM etc. were used to systematically analyze the three alloys, whichare identified to be new multicomponent quasicrystals. In this paper, thermalstability and phase transformation at high-temperature of the quasicrystallinepowders were also investigated.
