Commercial pure Titanium (CP-Ti) was processed by cryo-rolling with a thickness reduction of 20% and 50% at a cryogenic temperature (T = –196°C). It was found that cryo-rolling to the total reduction of thickness 50% leads to form ultra-fine grains. The results showed that strength and hardness were enhanced by decreasing grain size. Both strength and hardness of the cryo-rolled CP-Ti were noticed higher than as-received material. The mechanical properties of the cryo-rolled 20% and 50% were significantly increased: the yield strength by 9% and 45%, and the ultimate tensile strength by 26% and 60%, respectively, compared to as-received CP-Ti. While the elongation was decreased by 38% and 78% compared with the as-received CP-Ti.
