A Review-Additive Manufacturing of Intermetallic Alloys Based on Orthorhombic Titanium Aluminide TiAlNb.

Titanium alloys based on orthorhombic titanium aluminide TiAlNb are promising refractory materials for aircraft engine parts in the operating temperature range from 600-700 °C. Parts made of TiAlNb-based alloys by traditional technologies, such as casting and metal forming, have not yet found wide application due to the sensitivity of processability and mechanical properties in chemical composition and microstructure compared with commercial solid-solution-based titanium alloys. In the last three decades, metal additive manufacturing (MAM) has attracted the attention of scientists and engineers for the production of intermetallic alloys based on TiAlNb.
