A titanium alloy composite material including dispersed carbon fibers coated with a layer containing an element which forms a carbide in reaction with carbon, and the carbide formed thereby, in crystal grains of the titanium alloy. The element which forms a carbide in reaction with carbon is preferably at least one of silicon (Si), chromium (Cr), titanium (Ti), vanadium (V), tantalum (Ta), molybdenum (Mo), zirconium (Zr), boron (B), and calcium (Ca). The carbon fibers are preferably carbon nanotubes, vapor-grown carbon fibers, or a mixture thereof. The titanium alloy composite material has excellent mechanical strength, such as tensile strength, Young's modulus, toughness, and hardness.
A titanium alloy composite material including dispersed carbon fibers coated with a layer containing an element which forms a carbide in reaction with carbon, and the carbide formed thereby in crystal grains of the titanium alloy.
A method of producing a titanium alloy composite material, comprising:
A titanium clad material comprising a titanium alloy composite material including dispersed carbon fibers coated with a layer containing an element which forms a carbide in reaction with carbon, and the carbide formed thereby, in crystal grains of the titanium alloy, and a titanium alloy having a higher fracture toughness than the titanium alloy of the composite material, sinter bonded to one another.
A method of producing a titanium clad material comprising:
