| Abstract Scope |
Additive repair of aerospace components is gaining ever-increasing attention due to strategic material cost and manufacturing sustainability issues. This research evaluated the feasibility of an experimentally simulated electron beam wire fed (EBWF) additive repair using Ti-6Al-4V thin walls (3 mm) to emulate fan blade repair. The focus of this work was to understand the effect of the initial substrate microstructure and residual stress profile on the final deposit properties. The research included several substrate sample conditions with different initial microstructures and residual stress profiles that were manufactured by both additive and conventional manufacturing methods. Residual stress and distortion profiles of each substrate condition were analyzed pre-and-post-EBWF deposition. Alterations in the grain structure of the substrate plates were investigated through microstructural characterization. Mechanical properties and deformation behaviors were characterized to allow a comprehensive understanding of the inter-relationships between process, structure, and performance. |
