Electron Beam Additive Manufacturing (EBAM) is a promising method to produce large-scale near-net-shape structural metallic components. While the ability to produce complex geometries in a near-net shape fashion is attractive (potentially) from not only an economics perspective but also a reduction in the time between design and part realization, the microstructures, and material properties which result from this process are not well understood at this time. The rapid melting and solidification of material, followed by cyclic heating, remelting/resolidification, and cooling generates a complex thermal history, resulting in potentially far from equilibrium microstructures. This article reviews progress towards understanding the influence of the EBAM process on the microstructure and properties of Ti-6Al-4V. Advanced characterization and quantification techniques were employed to study the size, morphology, and distribution of microstructural features. These attributes are incorporated into a neural network model to predict the mechanical properties, and the properties are presented and compared against those observed for wrought structures.
