Section: claims

1. A radiation resistant high-entropy alloy having an FCC structure, defined by a general formula of Fe1Co1Ni1V1Mo1TixCry, wherein 0.1≤x≤0.15, and 0.1≤y≤0.2, and a subscript of each element in the general formula represents a molar ratio. 2. The radiation resistant high-entropy alloy having an FCC structure of claim 1, wherein the radiation resistant high-entropy alloy is integrated in fuel cladding materials in nuclear power plant reactors and/or components of reactor cores of a nuclear power plant. 3. A method of producing a radiation resistant high-entropy alloy having an FCC structure, comprising:stacking Fe, Co, Ni, V, Mo, Ti, and Cr according to a proportion, andconducting vacuum levitation melting or vacuum arc melting, to obtain the radiation resistant high-entropy alloy having an FCC structure,wherein the radiation resistant high-entropy alloy having an FCC structure produced is defined by a general formula of Fe1Co1Ni1V1Mo1TixCry, wherein 0.1≤x≤0.15, 0.1≤y≤0.2, and a subscript of each element in the general formula represents a molar ratio. 4. The method of claim 3, wherein the step of vacuum levitation melting or vacuum arc melting comprises:during fusion alloying, placing Ti, Fe, Co, and Ni at the bottom, and placing Mo, Cr, and V at the top. 5. The method of claim 3, wherein in the vacuum levitation melting or vacuum arc melting, vacuumizing is conducted to reach 5×10−3 Pa to 3×10−3 Pa, and back-filing with argon gas is conducted to reach 0.03 MPa to 0.05 MPa. 6. The method of claim 3, wherein alloy ingots are turned and melted five to seven times during the vacuum arc melting. 7. The method of claim 3, wherein alloy ingots are turned and melted four to six times during the vacuum levitation melting. 8. The method of claim 3, wherein Fe, Co, Ni, V, Mo, Ti, and Cr are all industrial grade pure raw materials with a purity of over 99.5 wt. %.
