57Fe Mossbauer spectra of highly supersaturated Al-Fe alloys containing 0.5, 1, 3 and 5 at % Fe were obtained. The spectra were interpreted as a superposition of a single line due to isolated Fe atoms and broad quadrupole split lines due to Fe associations and precipitations. From the area ratio between single line and doublet, it was found that the enhanced formation of these associations and precipitations occurred in all specimens.
