摘要：

In order to improve the mechanical properties of pure titanium, a series of pure titanium was processed by cryogenic rolling (CR) and annealing. The annealing was carried out in the temperature range of 420 degrees C to 530 degrees C, and the annealing time was 5 min to 15 min, respectively. It showed that CR at the liquid nitrogen temperature could significantly enhance the strength, but the ductility simultaneously decreased. Subsequent annealing could recover some of the ductility while the strength lowered. Compared with other samples, the sample annealed at 450 degrees C for 10 min had the best combination of strength and ductility because of the bimodal distribution of grain sizes.
