Conference paper


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.
