Lightweight titanium aluminides are becoming increasingly interesting as high temperature structural materials. Advantageous properties like high strength and creep resistance combined with high corrosion and wear resistance increase their attractiveness for aircraft applications like e.g. low pressure turbine blades. Additive manufacturing (AM) technologies provide the possibility for near-net-shape production as well as repair of worn parts and therefore can contribute to reduction of consumption and costs of material, tooling and finishing. The typical high brittleness and oxygen affinity of TiAl cause special requirements for processing with AM. In this work the defect free workability of γ-TiAl alloys with both Laser Metal Deposition (LMD) and Selective Laser Melting (SLM) is demonstrated. Relationships between processing and resulting material characteristics are investigated.
