Two types of aluminum-titanium-vanadium ternary intermetallic compounds have been prepared by arc melting under argon atmosphere. Their compositions were nominally AI65Ti25V10 and Al57 Ti 22V21; the numbers represent the molar fractions in mol%. These two alloys stand within the gamma-phase field where the L10 face-centered tetragonal structure is produced. Metallographic structure and mechanical properties have been investigated. It is suggested that vanadium addition to titanium aluminides and titanium trialuminides can enhance their strength.
