Abstract: The Al–Cr–Fe phase diagram was studied in the compositional range of 50–100 at% Al and partial isothermal sections were determined at 1160, 1100, 1075, 1042, 1000, 900, 800 and 700 °C. In the low-Al part of the studied compositional region the isostructural high-temperature Al–Cr and Al–Fe γ1-phases form a continuous region of solid solutions. Both binary Al13Fe4 and Al5Fe2 were found to dissolve up to 6.5 at% Cr while Al2Fe was found to extend up to 4.1 at% Cr. The solid solutions based on the Al–Cr γ2 and μ phases were determined to reach 35.2 and 1.3 at% Fe, respectively. The dissolution of Cr in the Al–Fe binaries only slightly influences their Al concentrations, while the Al–Cr binaries exhibit decreasing Al concentration with increasing Fe concentration. The Al–Cr η-phase dissolves up to 5 at% Fe, which results in a sharp decrease of its Al concentration and increase of melting temperatures. The earlier reported existence of a ternary decagonal D3-phase and three complex periodic phases O1, H and ε was confirmed and their compositions at different temperatures were specified.
