Abstract

Grain boundary character distribution and texture evolution of Ti-45Nb wires were investigated during the cold-drawn process. The results revealed that the fiber microstructure formed along drawing direction after cold-drawn process. The <110> fiber texture formed and the intensity enhanced by increasing the strain from 90% to 98% during the cold-drawn process. A large amount of high angle grain boundaries (HAGB) occurred at a large strain state of 90%, which was resulted from the rotation of the initial β grains. By increasing the strain to 98%, the fraction of low angle grain boundaries (LAGB) increased remarkably by the formation of the subdivided grains.
