Prospects for industrial use titanium aluminide in aeroengine

The possibility of partial replacement of heat-resistant nickel alloys in the manufacture of components of gas turbine engines for titanium aluminide. In the range of operating temperatures of 600 ... 900 °C for specific strength they surpass all nickel superalloys. The problems of forming parts of gas turbine engines of titanium aluminides. Low plasticity characteristic of intermetallic titanium complicates their technological processing and is a major obstacle widespread industrial use. The possibility of using welding technology in the manufacture of products made of titanium aluminides. Methods for fusion welding do not provide full-strength welds. Pressure welding methods provide more opportunities formation of secure connections.
