| Abstract Scope |
Boron additions strengthen titanium alloys; however the effect on their corrosion resistance is only recently being understood. Significant grain size refinements have been observed in the base Ti-6 Al-4 V alloy even with trace boron additions (0.05-0.4 wt%). Heat treatment of Ti-6 Al-4 V containing 0.05-0.4 wt% B additions resulted in changes in yield strength, ultimate tensile strength and fracture toughness values. The effect of the heat treatments and the subsequent microstructural changes on the corrosion resistance of these alloys is unknown. This information is crucial in determining the suitability of these alloys for load bearing applications in a corrosive medium, e.g., structural bio-implants. In this study, we focused on characterizing the corrosion resistance of titanium-boron alloys in 0.9 wt% sodium chloride (saline) solutions. Nine |
