Abstract

Based on the data obtained during study of the Hf–Ru–Rh alloys at 0−50 at. % Hf in as-cast state and after annealing at subsolidus temperatures using physicochemical analysis techniques, vertical sections of the Ru–HfRu–HfRh–Rh partial system are constructed for the first time along the isopleths at 10, 25, 33.00 ± 0.33, and 37.5 ± 0.5 at. % Hf as well as at 5 at.% Ru. These sections demonstrate peculiarities of the phase diagram, in particular, temperature ranges of alloy crystallization and nature of phase transformations.
