Recrystallization behavior of commercially pure titanium during hot deformation

Journal Article


Abstract


  • Isothermal hot deformation tests were performed on commercially available titanium (Grade 2) samples at high temperatures using a Gleeble 3500 thermo-mechanical simulator. The flow stress curves and microstructures of the samples were investigated after hot deformation and quenching processes to evaluate dynamic recrystallization process, respectively. The results show that significant influence of deformation temperature and strain rate on deformation structure and flow curves can be observed during deformation. Meanwhile, dynamic softening behavior on the material can be observed during hot deformation tests. The degree of softening is related with temperature, strain rate and un-loading time. Compared with microstructure of pure Ti without deformation, the grain size under deformation is refined greatly.
