{112¯4} deformation twinning in pure Ti during dynamic plastic deformation

► Pure Ti samples were deformed by dynamic plastic deformation (DPD). ► There were four and tree types of deformation twins during DPD and quasi-static compression, respectively. ► {112¯4} twinning was only found in DPD samples. ► The high strain rate affected the formation of {112¯4} twinning
