Zusammenfassung:	The invention relates to an intermetallic alloy based on titanium, comprising, in atomic percentages, between 16% and 26% of Al, between 18% and 28% of Nb, between 0% and 3% of a metal M selected from Mo, W, Hf, and V, between 0% and 0.8% of Si, between 0% and 2% of Ta, and between 1% and 4% of Zr, with the condition Fe+Ni < 400 ppm, the remainder being Ti, the alloy also having an Al/Nb ratio in atomic percent of between 1.05 and 1.15. L'invention concerne notamment un alliage intermétallique à base de titane comportant, en pourcentages atomiques, 16 % à 26% d'AI, 18 % à 28% de Nb, 0 % à 3% d'un métal M choisi entre Mo, W, Hf, et V, 0 % à 0,8% de Si, 0 % à 2% de Ta, 1 % à 4% de Zr, avec la condition Fe+Ni < 400 ppm, le reste étant Ti, l'alliage présentant en outre un rapport en pourcentage atomique Al/Nb compris entre 1,05 et 1,15.
