Superplastic forming is an effective way to manufacture complex-shaped parts of titanium-based alloys. This paper studies the influence initial microstructure and its strain-induced evolution on superplastic deformation behavior formability a alloy. Two types Ti–Al–V–Mo alloy samples having different fraction recrystallized grains before start were studied. The behavior, including strain harden...

A continuum theory for non-Newtonian flow of a two-phase composite containing rigid inclusions is presented. I t predicts flow suppression by a factor of (1 V)p, where V is the volume fraction of the rigid inclusion and q depends on the stress exponent and the inclusion shape. Stress concentrations in the rigid inclusion have also been evaluated. As the stress exponent increases, flow suppressi...
