Abstract
A refractory composite material usable in making gas-turbine blades for aviation applications. The composite material comprises a nickel-based superalloy matrix containing cobalt, aluminum in the form of a Ni.sub.3 Al precipitate, and tungsten, and a reinforcing phase of oriented monocrystalline niobium carbide fibers formed in situ during production, by unidirectional solidification. The composition of the composite material by weight expressed in percent is: PA1 Co -- 20-30% PA1 Cr -- 6-15% PA1 W -- 7-10% PA1 Al -- 3-6% PA1 Nb -- 4-6% PA1 C -- 0.4-0.65% PA1 Ni balance to 100.
