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.
