    摘要： Microcracks in fiber-reinforced/titanium aluminide matrix composite materials are inhibited by employing a matrix comprising a titanium aluminide alloy having (1) from ten to twelve atomic percent niobium and (2) a critical admixture of from two to six atomic percent of a member selected from a group consisting of molybdenum, tungsten and vanadium. The tendency of the fiber/matrix interfacial reaction to increase the stability of the Alpha 2 phase in the matrix adjacent to the interface and the tendency to form a "beta phase depletion zone" are unexpectedly negated. Suppression of the beta depletion zone formation inhibits the formation and growth of interfacial microcracks, and allows the fabrication of crack-free titanium matrix composite materials. The need for an extraneous beta phase stabilization treatment at the fiber/matrix interface is eliminated.

    摘要： A method for asymmetrically consolidating a ring structure having a filamentary reinforcement embedded in a plasma sprayed deposited matrix is taught. The method involves fabricating a filament reinforced plasma sprayed deposit matrix structure and asymmetrically consolidating the structure. The asymmetric consolidation is accomplished by placing a thicker and/or stronger can surface on the outer portions of the ring structure and a thinner and/or weaker can structure on the inner and side surfaces of the reinforced ring structure. The HIPing of the reinforced ring structure with the asymmetric can results in a preferential compaction of the ring from the inside toward the outside and avoids the buckling of and damage to the reinforcement filaments on the outer portions of the structure.

    摘要： A method of manufacturing ingots for use in making objects having heat, thermal shock, corrosion and wear resistance by formulating a composition of about 17-80% TiB.sub.2 powder, about 0.0 to 4.0% Y.sub.2 O.sub.3 powder, and the balance of NiAl powder, the powders being thoroughly admixed, and placing the admixture into a mold in which it is subjected to a pressure of about 7000 psi and a temperature of about 1400.degree. C. for 20 to 140 minutes in an inert atmosphere, after which the mold is cooled and the ingot is removed and ready for use in manufacturing an object. In some applications the use of a ceramic filler material mixed with the powder is employed to improve the physical characteristics of the finished ingot.
