DOI: 10.1016/j.ijplas.2021.103108
Abstract: Abstract Achieving high superplasticity in single-phase Al alloys remains a challenge, since the fine-grained structure required for superplastic deformation coarsens rapidly in the absence of dispersed second-phase particles during tensile deformation at elevated temperatures. This… read more here.

DOI: 10.1016/j.jallcom.2016.09.170
Abstract: Abstract Fine-grained Ti-(42.5–43.5)Al-8Nb-0.2W-0.2B-(0–0.1)Y (in at.%) alloys with two different phase constituents (i.e., (α2+γ) alloy and (β/B2+γ) alloy) have been prepared by means of thermo-mechanical processing. Tensile tests were performed at 1000 °C under an initial strain-rate… read more here.

DOI: 10.1016/j.jallcom.2019.02.125
Abstract: Abstract This paper presents a new finite-strain and thermomechanically-coupled constitutive model for severe superplastic deformation of Ti-6Al-4V at elevated temperature. The kinematic hypothesis of this model is a multiplicative decomposition of the deformation gradient into… read more here.
