A thermodynamically stable quasicrystalline single phase with an icosahedral structure was found to be formed at an atomic composition of Al 65 Cu 20 Fe 15 in a fully annealed state as well as in a conventionally solidified state. The stable quasicrystal consisted of large grains with an average size of 0.2 mm after annealing for 48 h at 1118 K (0.98 T m ).
