Description

Ti-6-4 processed by L-PBF (Laser Powder Bed Fusion) is known to have an anisotropic microstructure due to the unidirectional build process, which leads to anisotropic ductility and fatigue behavior. Boron is known to be a nucleation starter within Titanium alloys, leading to a refinement in the microstructure. Within this work, the effects of in-situ alloying of Ti6Al4V and B on the microstructure, mechanical properties, and their anisotropy should be investigated.
Additionally, the same alloy system (Ti-6-4 plus Boron) will be investigated via Laser-Directed Energy Deposition (L-DED), and results from both AM technologies will be compared.
Furthermore, hybrid samples made of Ti-6-4 produced by a combination of L-PBF and L-DED will be built and investigated regarding their mechanical properties, especially in the transition zone.
