dc.description.abstractIn the present study, compression tests were performed at a strain rate of 0.001 to 0.1 s(-1) and in the range of 600 degrees C to 900 degrees C to investigate the high temperature deformation behavior and flow stress model of commercially pure titanium after severe plastic deformation (SPD). It was found that the effects of temperature and strain rate are significant in dictating the steady state flow stress levels. Flow accompanied by thermal softening was observed due to a combination of dynamic recovery and recrystallization for deformation at or above 600 degrees C. Furthermore, microstructural evolutions of the as processed and hot deformed material were investigated. Based on constitutive equations, the flow stress was modeled for this light ultra-fine grained (UFG) material. The validity of the model was demonstrated with satisfactory agreement in light of the experimental mechanical behavior.en_US
