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.

Claims

exact text as granted — not AI-modified
1 . A titanium alloy material comprising 0.005-0.10 mass % of ruthenium (Ru), 0.005-0.10 mass % of palladium (Pd), 0.01-2.0 mass % of nickel (Ni), 0.01-2.0 mass % of chromium (Cr), 0.01-2.0 mass % of vanadium (V), with the remainder including titanium (Ti) and inevitable impurities. 
     
     
         2 . The titanium alloy material according to  claim 1  further comprising at least one member selected from the group consisting of 0.005-2.0 mass % of aluminum (Al), 0.005-2.0 mass % of silicon (Si), and 0.005-2.0 mass % of iron (Fe). 
     
     
         3 . The titanium alloy material according to  claim 1  further comprising at least one member selected from the group consisting of 0.005-0.10 mass % of osmium (Os), 0.005-0.10 mass % of rhodium (Rh), 0.005-0.10 mass % of iridium (Ir), and 0.005-0.10 mass % of platinum (Pt). 
     
     
         4 . The titanium alloy material according to  claim 2  further comprising at least one member selected from the group consisting of 0.005-0.10 mass % of osmium (Os), 0.005-0.10 mass % of rhodium (Rh), 0.005-0.10 mass % of iridium (Ir), and 0.005-0.10 mass % of platinum (Pt). 
     
     
         5 . A structural member using the titanium alloy material of any one of  claims 1  to  4 . 
     
     
         6 . A container for radioactive waste using the titanium alloy material of any one of  claims 1  to  4 .
