Abstract
The constitution of the AlâPdâPt alloy system was studied above 35 at.% Al at 700, 780, 900 and 1100 °C. The experiments revealed the formation of wide extensions of the binary AlâPd and AlâPt phases but no ternary phases. Continuous regions are probably formed between the isostructural phases Al4TM, Al21TM8, high-temperature AlTM, low-temperature AlTM and Al3TM5 (TM = Pd or Pt). The continuity between the Al3TM2 phases was revealed at 900 °C, while at 1100 °C the regions mutually extended from Al3Ni2 and Al3Pd2 are separated by the ternary extension of Al2Pt. The latter phase was found to dissolve up to 24 at.% Pd, which resulted in a sharp decrease of its Al concentration. The AlâPd ε-phase was found to extend up to 18 at.% Pt at practically constant Al, while the AlâPt ξ-phase was found to extend up to 7 at.% Pd.
