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 Ti.sub.3 Al titanium aluminide having this level of ductility. The composites have good resistance to thermal cyclic fatigue.
Claims7
A titanium alloy matrix fiber reinforced composite material comprising at least one layer of high strength reinforcing fibers embedded in a matrix of Ti.sub.3 Al material, said matrix material having at least 10% room temperature ductility and improved resistance to thermal cyclic fatigue.
