Abstract: A titanium alloy matrix fiber reinforced composite made from titanium alloy sheet processed to have ductility up to about 35 %. Of particular usefulness is the composite having a Ti3A1 titanium aluminide having this level of ductility. The composites have good resistance to thermal cyclic fatigue. Preferred reinforcing fibers are silicon carbide. The processing involves multiple working steps below the beta transus with intervening thermal annealing steps, also at temperatures below the beta transus.
