| Abstract Scope |
Wire-feed Electron Beam Additive Manufacturing (WEBAM) is an advanced metal additive manufacturing technique that enables large-scale component fabrication in a vacuum environment, minimizing contamination, while offering deeper penetration, higher energy efficiency, and reduced hydrogen absorption compared to laser- or powder-based directed energy deposition methods. This study evaluates the mechanical performance of Ti-6Al-4V components produced by WEBAM, focusing on fatigue behavior as a function of process parameters. We fabricated rectangular samples, approximately 185 x 185 x 110 mm, at two different build speeds, either 7.5 lbs/hr or 15 lbs/hr. Test specimens were selected from different locations and orientations in the build. Tensile and fatigue properties were measured, and the properties were interpreted in terms of the process parameters, machine sensors data, and microstructure. The goal of the work is to develop methods for process-property development and to determine whether WEBAM-fabricated Ti-6Al-4V can meet the performance standards of wrought materials. |
