| Abstract Scope |
Elevated temperature deformation processing and heat treatments of a MoNbTi alloy are explored to develop techniques for difficult to process refractory alloys. In this work, upset forging and heat treating were performed to evaluate deformation mechanisms, homogeneity of stored energy, and resulting recrystallization behavior. Varied strain pathways (uni- vs. multi-axial) were compared to investigate effectiveness of alternative processing strategies to reduce grain size and texture. Interrupted elevated temperature compression and electron back scatter diffraction (EBSD) characterization were utilized to evaluate deformation mechanisms and resultant texture. Heat treatments after deformation were performed to study static recrystallization kinetics and evolution of oxide topology. An outlook on considerations for research scale processing techniques to aid novel alloy development are included. |
