Overview: Future aerospace applications require materials with ever increasing temperature and load-bearing capabilities. Continuous SiC fiber-reinforced titanium metal matrix composites (TMCs) exhibit the potential for meeting these requirements and are particularly attractive for use in aircraft gas turbine engines owing to their specific mechanical properties at high temperature. Changing conventional titanium alloys matrices (Ti-6Al-4V, Ti-6Al-2Sn-4Zr-2Mo) to a titanium aluminide of the orthorhombic type (Ti2AlNb) which possesses a higher temperature capability will extend potential aero-engine applications of TMCs. Two different orthorhombic alloys were considered in the present study and compared to a Ti-6Al-2Sn-4Zr-2Mo matrix.
