| Abstract Scope |
Due to their low density, high corrosion resistance, and biocompatibility, titanium and titanium alloys are highly attractive for many industries, including notably aeronautics and biomedical fields. However, the mechanical strength of Ti-based materials can be too limited for certain applications at room temperature, and even more so at high temperatures. In an original approach, this study aims to investigate the impact of adding small amounts of alloying elements on the microstructure and mechanical properties of titanium. Among various beta-stabilizing elements, the effect of micro-alloying with rhenium is particularly investigated. The results obtained highlight that a limited addition, < 1 wt.% of Re, can more than double the mechanical strength while maintaining a high reserve of ductility. The associated microstructural analysis shows that the addition of Re induces the presence of nanometric beta-phase particles (both intra- and inter-granular) as well as a significant refinement of the grain size. |
