Abstract The results of a systematic investigation of the effects of microstructure/substructure on the secondary creep behaviour of α2-based titanium aluminide alloys are presented. This includes a study of the effects of heat treatment on the steady-state creep behaviour 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 data obtained for conventional high-temperature near-α titanium alloys and β-forged Ti–24Al–10Nb–3V–1Mo.
