Abstract: The structure of Al₃₃Cu₁₀Fe₂₄Ti₃₃ alloy powders has been studied by transmission electron microscope(TEM).In the specimens heated at 800℃,decagonal quasicrystalline phase(T phase) and Al solid solution polycrystals have been found.Moreover,two cubic phases and one hexagonal phase have also been found and determined.One cubic phase(F) belongs to FCC lattice with a=1.15 nm,the other cubic phase(B) belongs to BCC lattice with a=0.86nm.The hexagonal phase(H) belongs to hexagonal lattice with a=0.74 nm and c=0.48 nm.
