| Abstract Scope |
Until recently, additive manufacturing (AM) research on niobium alloy C103 focused solely on powder-based methods, which generally suffer from lower deposition rates, smaller production volumes, and reduced feedstock efficiency compared to wire-based AM. In this work, a Meltio M450 system modified with a high-temperature build-plate heater was used to establish processing parameters for depositing C103 wire onto C103 plate. Single-track studies guided parameter selection for thin-wall builds; evaluating working distance, laser power, scanning speed, and substrate temperature. Substrate heating proved essential for minimizing solidification cracking and ensuring adequate interlayer fusion. Process–microstructure–property relationships for as-printed and annealed samples were characterized via SEM-EDS, EBSD, hardness testing, and room-temperature tensile testing. |
