Influence of strain rate and crystallographic orientation on dynamic recrystallization of pure Zn during room-temperature compression

•The primary DRX mechanisms of pure Zn during RT compression are CDRX accompanied by TDRX.•With increasing strain rate, the profuse twins and dislocations movement facilitate TDRX.•The CDRX mechanisms in grains of different orientation are varied considerably.•The propensity for basal and pyramidal slips and P/B ratio determine CDRX mechanisms.
