The Al-Cu-Fe system is known to contain quasicrystalline phase which was reported by many scientists as the stable phase. In this work, the effect of the processing conditions on the formation of quasicrystals and other intermetallics in this systems was studied. The experimental alloys were prepared by casting, water quenching, melt spinning and SHS (Self-propagating High-temperature Synthesis) methods. It has been found that the increase of the cooling rate promotes the formation of the quasicrystalline phase. The thermal stability of the quasicrystals was studied by annealing of the SHS product at 300 and 500°C.
