Abstract

The Al-Ni-Pt phase diagram was studied in the compositional region from 50 to 100 at.% Al. Isothermal sections were determined at 1000, 900 and 790 °C. At 1000 °C the Al ₂Pt phase was found to extend up to ∼Al ₅₃Ni ₂₃Pt ₂₄ composition, separating the (Al ₃Pt ₂) and (Al ₃Ni ₂) phase fields. Two ternary structures were revealed. The one forming between ∼Al ₇₅Ni ₃Pt ₂₂ and Al ₇₅Ni ₉Pt ₁₆ is rhombohedral isostructural to Al ₂₈Ir ₉ and the other forming between ∼Al ₇₃Ni ₈Pt ₁₉ and Al _72.5Ni ₁₈Pt _9.5 has an orthorhombic ε ₆ structure typical of Al-Pd and Al-Rh.
