Abstract

This work is focused on the experimental investigation of intermetallic phases in Al60Co29Cu11, Al63Co24Cu13, and Al67Co20Cu13 complex metallic alloys at near-equilibrium conditions. The alloys were long-term annealed at temperatures between 800 and 1150 C and subsequently rapidly cooled to fix their high-temperature microstructures. Annealing temperatures were chosen with respect to the results of differential thermal analysis. Particular samples were studied by X-ray diffraction, scanning electron microscopy including energy dispersive X-ray spectroscopy and electron backscatter diffraction, and transmission electron microscopy. In the microstructures of particular samples, various combinations of D, B2, m, Al5Co2, and Θ-Al2Cu phases were identified depending on both bulk metal composition and thermal history.
