| Abstract Scope |
The refractory alloy Ta-2.5W is critical in high-temperature, high-stress environments such as aerospace and nuclear applications due to its strength and ductility. Understanding its thermomechanical behavior supports reliable components and informed material selection. As a BCC alloy, Ta-2.5W’s mechanical properties depend on temperature and strain rate, making quantification important for manufacturing. We present an experimental campaign on the mechanical properties of Ta-2.5W across a wide range of temperatures (25C to 1000C) and strain rates (10⁻³ to 100) via the use of a Gleeble GTC3800 thermomechanical testing system. Compression sample microstructure is observed via SEM/EBSD and Keyence. Special focus of this study was the influence of temperature and strain rate for optimization of forging conditions, cumulating in the creation of a detailed hot workability map.
