Ten alloys with metal compositions (at.%) ranging between (61-75)Al, (7-30)Pd, and (9-22)Co were investigated after annealing at 1020 °C for 500 h. In the investigation, both scanning electron microscopy including energy dispersive x-ray spectroscopy and x-ray diffraction were used. Various combinations of phases F, εn (shortcut for ε-family), U, V, Z-Al3Co, Al5Co2, δ, and β were identified in studied alloys. Partial experimental isothermal section of the Al-Pd-Co phase diagram for Al-rich corner at 1020 °C was proposed, containing homogeneity ranges of eight solid phases (F, εn, U, V, Z-Al3Co, Al5Co2, δ, and β) and liquid.
