Abstract

Based on the data obtained by metallography, x-ray diffraction, electronic microprobe and differential thermal analyses as well as by Pirani-Alterthum incipient melting technique, the solidus surface projection of the Ti–TiRh–AlRh–Al partial system is constructed on the composition triangle for the first time. The participation of two ternary compounds (τ1, Al67Ti27Rh6, with AuCu3-type structure and τ2, Al49.6Ti27.1Rh23.3,with Th6Mn23+1 -type structure) in phase equilibria is confirmed. Thirteen single-phase surfaces corresponding to solid solutions based on components and to the phases based on binary and ternary compounds are found on the solidus surface. This surface also contains 25 ruled surfaces bounding two-phase volumes as well as 13 isothermal planes that are constituents of invariant four-phase equilibria.
