Abstract By means of Mossbauer spectroscopy analyses, it is indicated that there are three kinds of configurations for Fe atoms corresponding to α-Al(Fe) and α-Al(Fe-Fe) solid solutions and α-Al13(Fe,V)3Si intermetallic compound in liquid-quenched Al-Fe-V-Si alloys. Except for the absence of α-Al(Fe-Fe) configuration in Al93.3Fe4.3V0.7Si1.7 alloy, the other Fe atomic configurations do not change during the annealing at 755 K for 500 h. However,the relative contents of these configurations have changed. The lattice parameters of α-Al matrix decreased with increasing Fe content (4.3, 5.4, 6.4 (atomic fracti0n, %)) for three RS Al-Fe-V-Si alloys in as-cast and heat-treated states. In addition, the possible configurations of V and Si atoms have been discussed by using the results of Mossbauer spectra and matrix lattice parameters.
