LAMELLAR-STRUCTURE TITANIUM-ALUMINIUM BASED ALLOY HAVING A BETA-GAMMA PHASE

摘要

The lamellar-structure titanium-aluminium alloy having a beta-gamma phase according to the present invention comprises between 40 and 46 at.% of aluminium (Al), between 3 and 6 at.% of niobium (Nb), between 0.2 and 0.4 at.% of a creep-property enhancer, 2 at.% of an anti-softening enhancer and a balance of titanium, and is produced by a vacuum arc melting method.
