Additively Manufactured CrMoTaTiV Refractory Alloy Demonstrates Excellent Radiation Resistance
A materials study released on July 31 shows that a research team used laser powder directed energy deposition (LP-DED) technology to fabricate a novel Cr₁₀Mo₂₅Ta₂₅Ti₁₅V₂₅ refractory complex concentrated alloy and systematically evaluated its structural stability and mechanical properties under irradiation environments. The study targets the demand for high-temperature, high-irradiation structural materials in next-generation nuclear fission and fusion devices. In the study, samples were subjected to 3.5 MeV Fe²⁺ ion irradiation at the Ion Beam Materials Laboratory of Los Alamos National Laboratory in the United States, at irradiation temperatures of room temperature and 650°C, with local doses reaching approximately 1.8, 6, and 18 dpa.
