Optimization of electron beam melting parameters for processing of Titanium Aluminide alloy

Abstract: Designers consider Gamma Titanium Aluminide alloy a potential new candidate for aero-engine manufacturing. However, Gamma Titanium Aluminide being an intermetallic alloy is hard to shape by conventional production routes such as machining and casting.  Electron Beam Melting, which is an additive manufacturing technique, is one of the suitable techniques to manufacture complex 3D parts from Titanium Aluminide. Nevertheless, this process is a complex one with many parameters and tuning it for new alloy systems remains a challenge. This talk is about how a compound term called `area energy input’ could be used to find out the optimum process window in Electron Beam Melting of Gamma Titanium Aluminide alloy.
