Generally Ti-10V-2Fe-3Al and Ti-6Al-4V alloys are solution heat treated below beta transus for use in order to avoid beta grain growth. But recently it was found that beta solution treated and over aged Ti-6Al-4V alloy has martensitic microstructures and good mechanical properties such as high fracture toughness and large crack propagation resistance. The effect of beta solution treatment on the mechanical properties of Ti-10V-2Fe-3Al have been hardly reported. In this study, the mechanical properties of beta solution treated and aged Ti-10V-2Fe-3Al was investigated and compared to conventional solution treatment. Then it is revealed that beta solution treatment gives better fracture toughness and crack propagation resistance comparing with alfa+beta solution treatment.
