Abstract
Al68Pd14.6Co17.4, Al69.8Pd13.8Co16.4, Al72Pd12.8Co15.2, Al73.8Pd11.9Co14.3, and Al76Pd11Co13 alloys annealed at 700 ∘C for 2000 h were studied. In the investigation, scanning electron microscopy including energy dispersive X-ray spectroscopy and electron backscatter diffraction, X-ray diffraction, and transmission electron microscopy were used. Altogether five near-equilibrium phases (β, U, Al5Co2, ε, Al9Co2) were identified. Transitions between β, U, and ε phases were also determined dependent on the alloy bulk metal composition. The experimental results were used to propose the partial isothermal section of the Al–Pd–Co phase diagram at 700 ∘C. The maximum solubilities at 700 ∘C of Pd in Al9Co2 and Al5Co2 were determined as 1.7 and 2.69 at.%, respectively.
