Objective
The combined resources of alloy producers, engine manufacturers and research organisations in France and the United Kingdom made it possible to carry out a detailed and exhaustive study of titanium aluminide alloys which have high potential for aeroengine applications. Production standard processing remains to be identified but the understanding achieved during this pre-competitive research project has demonstrated that the alloy possess the basic properties required for commercial exploitation.
R S Current high temperature titanium alloys are limited to temperatures around of 875K, where both creep strength and oxidation resistance restrict their endurance. The titanium aluminide, Ti**3A1, offers higher temperature capability but suffers from poor fracture properties due to its having an ordered structure. Possibilities exist for improving the fracture properties while maintaining the superior creep and oxidation properties by alloying but little is understood regarding the effects of alloying additions.
This project will study the effects of impurity elements, alloying additions and thermomechanical processing on the microstructure mechanical properties of Ti**3A1 alloys. The improved understanding will be used to design an optimum alloy for more extensive process and mechanical property evaluation. The main objectives are to :
(i) develop a European-sourced alloy based on Ti**3A1 with optimum levels of impurity elements/alloying additions for use at high temperatures.
(ii) establish the processing parameters necessary to produce 2 mm thick sheet and isothermal forging for typical structural application.
(iii) asses the potential benefits of the optimized composition for structural components.
The project will develop a generic understanding of Ti3Al alloys that can applied to future materials for specific applications.
