摘要	New nanocomposite Al(93.3-x)Fe(4.3)V(0.7)Si(1.7)Mm(x) (x = 0.5, 1, 3) materials have been made by melt-quenching. The nanophase structural features and the component configurations have been investigated by X-ray diffraction, transmission electron microscopy and Mossbauer effect spectroscopy. The results show significant lattice contraction in alpha-Al with increasing Mm content, and there are different nanometer-sized particles corresponding to alpha-Al-13(Fe,V)(3)Si and Al(8)Fe(4)Mm mixed phase for x = 0.5, only Al(8)Fe(4)Mm for x = 1 and Al(20)Fe(5)Mm for x = 3. The inherent Fe atomic environment in the Al(20)Fe(5)Mm quasicrystalline phase is characterized by a distribution of electric quadrupole splitting, which is shown to be well described by a Gaussian shape. The lattice contraction is believed to be correlated with the variation of component configurations in alpha-Al solid solution.
