Abstract
The melting diagram and reaction scheme (Scheil diagram) of the Al–Ti–Pt system have been constructed for the first time in the composition range 0–50 at.% Pt using the experimental results for as-cast alloys and alloys annealed at subsolidus temperatures. It is established that ternary compounds τ3, τ4, and τ8 form congruently with participation of the liquid phase and compounds τ1, τ2, τ5, τ6, τ7, τ9, and τ11 by peritectic reactions. All compounds take part in phase equilibria with participation of the liquid phase, forming 31 four-phase and 28 three-phase invariant equilibria at temperatures from 1410 to 660°C.
