Recent high-strain-rate experimental results have shown an anomalous response by commercially pure titanium at relatively high temperatures: for a fixed high strain rate and a suitable strain, the flow stress which is a monotonically decreasing function of the temperature, suddenly begins to increase with increasing temperature, and then begins to decrease, displaying a dynamics strain-aging behavior. This phenomenon may be caused by the interaction between moving dislocations and mobile point defects in the dislocation core area.
