| Abstract Scope |
Herein, we present findings from an experimental campaign on evaluating deformation behavior of TZM at elevated temperatures (600 °C to 1000 °C). TZM and other BCC refractory alloys exhibit mechanical behaviors that are dependent on both strain rate and temperature. To elucidate these sensitivities, we perform compression tests of TZM on a thermo-mechanical simulator (Gleeble) over a range of temperatures (600°C to 1200°C) and strain rates (10⁻³ to 100 s⁻¹). Thereafter, we utilize SEM/EDS, EBSD, and XRD to corroborate corresponding microstructural changes. Combined, these experiments provide insight into the strain-dependent behavior of TZM at elevated temperature. As such, these studies provide perspective on aging behavior and inform future work for understanding high-temperature creep in refractory alloys.
