| Abstract Scope |
This study investigates the fabrication of TiNbVZr alloy components through laser-based Directed Energy Deposition (DED). Atomized powder derived from a master alloy serves as the feedstock material. Recognizing the inherent susceptibility of TiNbVZr alloys to cracking during the solidification and subsequent cooling stages, the deposition process was meticulously optimized to minimize the formation of detrimental cracks. A comprehensive suite of microstructural characterization techniques was employed, including elemental distribution analysis and X-ray diffraction for phase identification, to elucidate the influence of processing parameters on the resulting microstructure. Furthermore, mechanical properties, encompassing tensile strength, yield strength, and ductility, were rigorously evaluated at both room temperature and elevated temperatures to assess the performance and suitability of the additively manufactured components for intended service conditions. |
