| Abstract Scope |
This study uses C103 — a highly fabricable and commercially available niobium alloy — as a model system to investigate crystallographic texture evolution in laser powder bed fusion (LPBF) of BCC refractory metals, a key factor in achieving tailored anisotropic mechanical properties. A variety of volumetric and thin-walled geometries were fabricated to observe the effects of scan strategy, part geometry, and a volumetric energy density up to 700 J/mm³ on grain size and bulk orientation. Preliminary results indicate that varying local thermal gradients and melt pool dynamics under different printing conditions significantly altered grain orientation distributions, yielding a transition from a strong <100> to <111> texture in the build direction. These findings suggest that grain orientation can be tailored through process design, which is critical for enhancing anisotropic mechanical performance in high-temperature environments. |
