      abstract     = {This work aims to identify the mechanisms of restoration
                      occurring in Ti-6Al-4V during hot plastic deformation and
                      subsequent heat treatment. The allotropic phase
                      transformation that occurs during cooling distorts the
                      interpretation of the restoration mechanisms taking place at
                      high temperatures. Therefore, analysis of deformed samples
                      by conventional microscopy have led to controversies in the
                      interpretation of the main dynamic restoration mechanism.
                      Additionally, static restoration of the microstructure can
                      occur during slow cooling, modifying the microstructure.
                      These facts were mainly the reasons why discontinuous
                      dynamic recrystallization and/or dynamic recovery has been
                      reported as the main dynamic restoration mechanism for
                      Ti-6Al-4V. In this work, we use in-situ synchrotron X-ray
                      diffraction combined with conventional microscopy to
                      determine the dynamic and static mechanisms of restoration
                      during and after deformation at different strain rates. The
                      results show dynamic recovery as main mechanism of
                      restoration during deformation in the β field, denoted by
                      sub-grain formation and a misorientation dependency of the
                      strain rate. After deformation, static recrystallization,
                      grain growth, and coarsening of the β grains can be
                      observed, especially at strain rates higher than
                      0.1s$^{−1}$. It is also demonstrated that the nucleation
                      of new grains can occur within the very first seconds of the
                      isothermal heat treatment.},
