Abstract
In an alloy having a Ti/Al ratio close to 52/48, good castability, by virtue of initial solidification in the .beta. phase, together with a sufficiently low density and a good oxidation resistance are obtained by introducing approximately 2 atom. % of rhenium and/or tungsten. These alloys can be used especially for the production of aeronautical turbomachine components.
