  • TITANIUM ALLOY MATERIAL, STRUCTURAL MEMBER, AND CONTAINER FOR RADIOACTIVE WASTE
    Publication number: 20100322817
    Abstract: It is an object of the invention to provide a titanium alloy material that exerts excellent corrosion resistance at a low cost in non-oxidizing environment such as a sulfuric acid environment, high temperature neutral chloride environment, or high temperature neutral chloride environment containing fluoride, a structural member using the titanium alloy material, and a container for radioactive waste using the titanium alloy material. Disclosed are a titanium alloy containing ruthenium (Ru): 0.005-0.10 mass %, palladium (Pd): 0.005-0.10 mass %, nickel (Ni): 0.01-2.0 mass %, chromium (Cr): 0.01-2.0 mass %, vanadium (V): 0.01-2.0 mass %, with the remainder including titanium (Ti) and inevitable impurities, and a structural member and a container for radioactive waste using the titanium alloy material.
