Abstract
A complex metallic alloy of the nominal chemical composition of 73.5Al-11Pd-15.5Co (at.%) was annealed at 1000 °C for 92 hours and then investigated with light microscopy, differential thermal analysis, scanning electron microscopy including energy and wavelength dispersive X-ray spectroscopy, and X-ray diffraction. The annealed samples (as-received state) and the samples after the thermal cycling in DTA were found to consist of the same microstructural constituents corresponding to the ternary U-phase, binary δ-phase, and a non-identified phase. The U-phase showed the compositional stability in a broad temperature range. The stabilization of the δ-phase during cooling was found to be accompanied with the decrease of cobalt content.

Key words
complex metallic alloys, Al-Pd-Co system, differential thermal analysis, U-phase, δ-phase
