Abstract Scope |
Vanadium, often considered a refractory metal, used for its high melting temperature and ductility, is metallurgically compatible with 304L stainless steel (SS304L) and Ti-6Al-4V. Stainless steel and titanium cannot be directly welded due to deleterious intermetallic phase formation. Therefore, vanadium is selected as an interlayer candidate. Laser beam directed energy deposition, or L-DED, is a melt-based additive manufacturing (AM) process. This work focuses on a parametric study of build parameters to optimize deposition properties of vanadium onto Ti-6Al-4V and SS304L to fabricate an interlayer, which is subsequently laser welded. The depositions and interlayer welds were characterized using scanning electron microscopy techniques (SEM imaging, EDS, and EBSD), hardness testing, and mechanical testing. Base-plate dilution was analyzed through the printed vanadium interlayer. Optimization of this technique has potential to drastically increase the weldability of many dissimilar materials using interlayers.
