AbstractAn aluminum based alloy, Al–Cu–Mg–Ti, was prepared via Osprey forming and extrusion. An elongated substructure toward the extrusion direction was observed after extrusion. Annealing treatments at temperatures up to 450 °C do not have an effect on such microstructure. Emergence of (sub)grains was observed at the highest annealing temperature of 520 °C which is associated to the misorientation increase of the (sub)boundaries. Tensile tests at different temperatures and also temperature-change tests were performed at strain rates of 10− 4, 10− 3 and 10− 2 s− 1. The analysis of data showed that the stress exponent coefficient increases from 5 at 500 °C to close to 14 at about 250 °C. The activation energy for deformation in both regimes was higher than that corresponding to aluminum self-diffusion. This creep behavior was associated with that of dispersion strengthened aluminum alloys.
