Abstract Scope |
Hybrid additive-subtractive manufacturing was used to manufacture a component in Ti-5553 (Ti-5Al-5Mo-5V-3Cr; wt.%), a high-strength near-beta alloy. The component was additively manufactured using laser powder bed fusion (LPBF) with interlayer peripheral milling. This approach allowed for the manufacturing of a component with a nearly enclosed volume featuring a high degree of accuracy and surface finish. Additive manufacturing parameters were adjusted to ensure high density and tailored mechanical properties after heat treatment. Coolant was not viable within the LPBF chamber, so the hybrid process was dry machining. Therefore, machining parameters were adjusted for this purpose and to accommodate this high-strength alloy with low thermal conductivity. After manufacturing, surface roughness measurements, X-ray computed tomography imaging, and microstructural characterization confirmed the efficacy of hybrid additive-subtractive manufacturing for Ti-5553 components. This study aims to show the potential of hybrid processing for producing non-trivial geometries with high accuracy requirements in Ti-5553. |
