Abstract

The results of a systematic investigation of the effects of microstructure/substructure on the secondary creep behavior of α₂-based titanium aluminide alloys are presented. This includes a study of the effects of heat treatment on the steady-state creep behavior of α₂+β-processed Ti-24Al-11Nb and Ti-25Al-10Nb-3V-1Mo at 540, 650 and 760°C, and an investigation of the effects of creep deformation on dislocation substructures in Ti-24Al-11Nb. The parameters that control secondary creep deformation are identified for both alloys, and the results are compared with previously reported data obtained for conventional high temperature near-α titanium alloys and β-forged Ti-24Al-10Nb-3V-1Mo.
