Electron beam freeform fabrication (EBF3) has the potential to produce large structures of aluminum, titanium, and other materials for the aeronautics and aerospace industries at higher, more cost-effective rates, compared to traditional manufacturing methods or other additive manufacturing processes. An important factor in commercializing EBF3 is ensuring that material properties of deposited products are comparable to those of wrought products. Using powder cored tubular wire (PCTW) technology and alloy theory, consumables were developed to control compositional variations in Al 6061 and Ti-6Al-4V structures produced by EBF3 and resulting deposits exhibited properties comparable to wrought products. Wire consumables have also been developed with powder cores designed to stabilize and refine β grain size by interrupting epitaxial grain growth in Ti-6Al-4V deposited structures. Aluminum matrix composite feedstock was developed using alloy theory and modelling techniques. These materials demonstrate the versatility of PCTW technology to provide materials tailored for aerospace applications.
