| 摘 要： | 本文研究了Al86-xFe14+x(x=0,2,4,6,8.5)准晶相合金的M?ssbauer谱,结果表明对x=0的Al86Fe14合金中以decagonal准晶相为主,谱拟合结果为两套面积积分比为1.69,近于黄金分割的亚谱组成,支持了准晶相为两种“Penrose”多面体组成的观点。当x增加时,出现的晶态含量增加;x=8.5时,几乎全部为晶态Al3Fe相。

| Abstract: | We report here the M?ssbauer study on Al86-xFe14+x( x= 0, 2, 4, 6, 8.5) quasicrystal alloys. The result shows that there is mostly decagonal phase for x = 0, it can be fitted by two sub-spectra which have area ratio of 1.69, close to the value of the golden mean. It implies that quasicrystal structure includes two kinds of "penrose polyhedrons". The alloys we studied here contain more crystalline phases when x increasing. The alloy with x = 8.5 contains almost only crystalline Al3Fe phase.
