Al-Cu-Fe alloys with a nominal composition of Al_{63}Cu_{24}Fe_{13}, Al_{62}Cu_{25.5}Fe_{12.5} and Al_{65}Cu_{20}Fe_{15} have been fabricated by solid-state reaction at 550, 650, and 750°C. The synthesized alloys mainly consist of icosahedral Al_{65}Cu_{20}Fe_{15}, body-centered cubic β-AlFe(Cu) and monoclinic λ-Al_{13}Fe_4 phases. After synthesis under optimal conditions the fraction of the icosahedral phase was 100, 80, and 85 weight per cent in Al_{63}Cu_{24}Fe_{13}, Al_{62}Cu_{25.5}Fe_{12.5}, and Al_{65}Cu_{20}Fe_{15}, respectively.
