| Abstract Scope |
This work investigates solid solution strengthening and deformation mechanisms in Molybdenum-Rhenium (Mo-Re) alloys within the single-phase BCC region. Bulk mechanical testing at quasi-static and dynamic strain rates revealed significant changes in strength and ductility with varying Rhenium content. Heat treatments from the as-worked to recrystallized states highlighted the role of micro-structure on mechanical response. Nanoindentation was used to quantify strain rate sensitivity, acƟvaƟon energy, and activation volume, providing insight into rate-dependent plasticity. Dynamic mechanical analysis via nanoindentation further enabled compositional mapping of local mechanical behavior. The integration of multi-scale mechanical testing techniques offers a comprehensive understanding of how Rhenium concentration and processing influence deformation behavior, guiding the design of high-performance refractory alloys. |
