Tensile and hardness tests have been at room temperature carried out of superplastically deformed Ti-15V-3Cr-3Sn-3Al alloys. Aging at 753K after superplastic deformation at 1023K, above the β-transus, yields faster hardening response and higher maximum hardness and tensile strength. The tensile strength as well as total elongation are increased by aging after solution treatment of the superplastically deformed specimens, i. e., the strength vs. elongation balance of the alloys is improved by the deformation and solution treatment and aging thereafter. This improvement might be mainly caused by the precipitation of fine and acicular α-phases nucleated in thermally stabilized subgrains.
