Selective laser melting (SLM) was applied to TiAl4822. Electron beam melting (EBM) has been a major additive manufacturing process for TiAl4822, but ductility is a technical challenge with EBM. This research investigates the microstructure and the tensile properties of TiAl4822 fabricated by a new SLM machine equipped with a heating unit. The elongation of the SLM specimen was 8.3 times that of the EBM specimen; this was attributable to the γ-phase−based homogeneous fine grains in the SLM specimen.
