Abstract

The invention concerns titanium aluminide based alloys produced by using cast iron and powder metallurgy techniques. Said alloys consist of Ti - z A1 - y Nb, y corresponding to the following formula: 44.5 atom % % <= y <= 45.5 atom % and x corresponding to the following formula: 5 atom % <= x <= 10 atom %, optionally additions of B and/or of C with contents ranging between 0.05 atom % and 0.8 atom %. Said alloy is characterized in that it contains a molybdenum (Mo) content ranging between 0.1 atom % and 3.0 atom %.
