Molybdenum base composite materials having high tensile strength and oxidon resistance at high temperatures are produced by piling in parallel and embedding silicon carbide fibers containing 0.01-20% by weight of free carbon, which have been produced by the specific method already disclosed in U.S. patent application Ser. No. 677,960, in molybdenum base metallic powders and by compressing and sintering the assembly.

Molybdenum base composite materials reinforced with continuous silicon

Cobalt or cobalt alloy composite materials reinforced with continuous silicon carbide fibers, which have a high tensile strength, a low elongation, a high Young modulus and a high tensile strength at a high temperature, are produced by filling spaces in piles of the continuous silicon carbide fibers containing 0.01%-30% by weight of free carbon with melted or powdery metallic cobalt or cobalt alloy and integrating the said fibers with the said metal.

Cobalt or cobalt alloy composite materials reinforced with continuous

Chromium base alloy composite materials having high corrosion resistance, idation resistance and tensile strength at high temperatures are produced by laminating and arranging silicon carbide fibers containing 0.01-20% by weight of free carbon, which have been produced by the specific method already disclosed in U.S. patent application Ser. No. 677,960, in volume fraction of 2-50% in chromium base alloy and by compressing and sintering the assembly.
