Abstract: A combination of unique properties of (i) high strength and stiffness at temperatures up to about 1500.degree. F., (ii) good room temperature mechanical properties including good ductility and (iii) improved resistance to matrix cracking is achieved in a titanium structure by forming a hybrid titanium alloy matrix composite in which the matrix consists of layers of at least two alloys, i.e. a high temperature-resistant titanium aluminide alloy and a ductile, lower modulus titanium alloy, that are bonded metallurgically to each other in various embodiments. A reinforcing material in the form of filaments, fibers or whiskers, e.g. silicon carbide, can be embedded within either or both types of the titanium layers.
