| Abstract Scope |
Electron Beam Additive Manufacturing (EBAM) has high deposition rates and big built envelopes which makes it a suitable additive manufacturing (AM) technology for the serial production of large metallic aeronautical parts. However, its complex periodic heat treatments with high temperature gradients produce heterogeneous and anisotropic microstructures throughout the built part compared to traditional technologies that has to be controlled in order to ensure its viability. In this study, a microstructural characterization of Ti-6Al-4V parts manufactured by EBAM technology is performed, providing a general idea of the main microstructural features that have to be taken into account for further improvement of this technology. After that, the influence of different key processing parameters on thermal history, microstructure and mechanical properties are investigated in order to reduce the large EBAM’s operating window to an operating zone where acceptable parts with the desired mechanical properties can be obtained. |
