In recent years significant advances have been made in the development of advanced titanium alloys for use in future gas turbine aero-engines. These advances have included the development of completely new titanium based materials, such as gamma titanium aluminides, orthorhombic alloys and non-burning titanium alloys. In the U.K. considerable effort has been concentrated on developing process routes for these materials for the production of cost-effective components with the optimum mechanical properties. The mechanical properties and behaviour of these advanced titanium alloys will be compared and contrasted with currently utilised materials and the opportunities for implementing these materials into future aero-engine designs will be discussed.
