Abstract

The Ti2AlNb-base alloy with superior high-temperature properties is one of the promising materials employed in the aviation and aerospace fields. The uniform viscous plastic constitutive equations were formulated to model the flow behavior of Ti2AlNb-based alloy at 910 to 970 °C. The evolution of dislocation density, grain size, phase volume fraction, damage, plastic deformation heating were considered by a set of physically based equations. The deformation and microstructure evolution of Ti2AlNb-based alloy tubular component during hot gas forming process was simulated using the established constitutive equations. The results show that the predicted microstructure evolution agreed well with the experimental results.
