Abstract
- In this study, the effect of phase conditions on the tensile behaviors of Ti-Cu alloys with Cu contents of 0, 10, 20, and 30 wt% is investigated by controlling the annealing temperature. An in-depth characterization of the alloy microstructure is performed using scanning electron microscopy and transmission electron microscopy. The results suggest that the mechanical properties of the Ti-Cu alloys are strongly affected by the Cu content in α lath, which is dependent on the volume of Ti 2 Cu rather than Ti 2 Cu itself. A high volume of Ti 2 Cu reduces the Cu content in α lath, resulting in high elongation and low strength. Ti 2 Cu has superior antibacterial properties when compared with that of the Cu-supersaturated α lath. This study provides new insights into the design of Ti-Cu alloys for application as a biomaterial. • Ti-Cu alloys were used to study effect of phase condition on tensile behavior. • Cu content in α lath strongly influences the mechanical properties. • High Cu content in α lath increased the strength but decreased the ductility. • Equiaxed Ti 2 Cu + α lath is beneficial for high ductility and antibacterial ability.
