Thermo-Calc software is used to model the composition diagram for alloys based on γ-TiAl of the systems Ti – Al – Mo – (4 – 10) at.% Nb and Ti – Al – Nb – X (X is Cr, Mo, V). The effect of alloying on critical points and sequence of phase transformations is established. Changes in phase composition in relation to alloy TNM-B1 temperature are analyzed using a polythermal section of the Ti – Al – Nb – Mo system.
