The continuous cooling from 1300 • C to ambient temperature by a differential thermal analyser was used to estimate the non-equilibrium evolution of phases in alloys Al67Pd14.6Co18.4, Al76Pd11Co13, Al71.7Pd14.4Co13.9, and Al67.4Pd20.6Co12. To compare non-equilibrium and near-equilibrium microstructures, the same alloys were also annealed at 850 • C for 500 h. Besides the differential thermal analysis, the X-ray diffraction, the scanning electron microscopy including energy dispersive X-ray spectroscopy, and the Vickers microhardness test were used in the investigation. Various combinations of phases β, U , δ, εn, F , Al5Co2, and Al9Co2 were identified in the alloys; there was no difference between continuously cooled and as-annealed conditions in the phase occurrence. The alloys, as sequenced above, were considered to solidify through phases β + V (concurrently), F , V , and β, respectively. Temperature ranges of solidification were also estimated. Based on the experimental results and other available data, the sequences of non-equilibrium phase transitions were proposed for several alloys of the still less-known Al-Pd-Co system.
