Abstract

The multiphase alloys with a high Al content and the presence of quasicrystalline phases are promising for aviation and space industry due to their low specific weight, high specific strength, corrosion resistance, and high tribological properties. An Al82Cu7Fe11 alloy ribbon has been obtained by spinning. It is shown by X-ray diffraction analysis that the alloy contains Al (sp. gr. Fm m), Al13Fe4 (sp. gr. С2/m), Al2Cu (sp. gr. I4/mcm), Al23CuFe4 (sp. gr. Cmc21), and decagonal quasicrystals (sp. gr. P105mc). The inhomogeneity of the ribbon surface is revealed by scanning electron microscopy. The presence of Al, Al13Fe4, and decagonal quasicrystals in the ribbon is found by transmission electron microscopy.
