Abstract Scope |
Additive manufacturing (AM) has the ability to create parts with complex alloy systems not always possible using traditional manufacturing methods. Research in the functionally graded material space is an emerging trend in the AM community. Samples of Ti-6Al-4V - Ti-6Al-4V-xW were created using a bespoke directed energy deposition AM system. Tungsten was chosen as the alloying element due to its grain refinement ability along with its considerable differences in properties compared to Titanium. Processing parameters were optimized following a design of experiments statistical tool for defect reduction (spherical porosity, chemical inhomogeneity, and lack of fusion defects), as well as characterizing properties (microstructural and mechanical). This processing-microstructure-property relationship can help with the understanding of other Titanium binary alloys as well as post deposition heat treatments. |
