FIELD: metallurgy.
SUBSTANCE: invention refers to alloys on base of titanium aluminides produced by melting or by power metallurgy with composition Ti-zAl-yNb where 44.5≤z≤45.5 atom % and 5≤y≤10 atom %; also composition contains molybdenum 0.1≤Mo≤3 atom % and has fine dispersed β-phase in γ-titanium-aluminide alloy in temperature range up to 1320°C. Alloy can additionally contain B and/or C at amount of 0.05≤B≤0.8 atom % and 0.05≤C≤0.8 atom %.
EFFECT: alloys possess high mechanical properties.
