Dislocation density based model for plastic deformation and globularization of Ti-6Al-4V

• A physically based model for the plastic deformation of Ti-6Al-4V is developed. • The model is calibrated using tests done at various temperatures and strain rates. • At low & medium temperatures, dislocation glide & climb are the dominant mechanisms. • At high temperatures, globularizatio...

• A physically based model for the plastic deformation of Ti-6Al-4V is developed. • The model is calibrated using tests done at various temperatures and strain rates. • At low & medium temperatures, dislocation glide & climb are the dominant mechanisms. • At high temperatures, globularization is also dominant. • The model can reproduce flow softening and stress relaxation behavior in Ti-6Al-4V.
