A Computational Study on Radiation Shielding Potentials of Eutectic High Entropy Alloys

Abstract

Eutectic high entropy alloy, a new kind of high entropy alloy, has great interest due to the widespread use in high temperature applications with perfect mechanical features. Our motivation to do this work is the absence of studies about the radiation shielding performances of this new type alloys. The aim of the work was to determine the photon protection parameters such as linear and mass attenuation coefficients, mean free path, half value layer, effective atomic number, fast neutron removal cross section and buildup factors of the eutectic high entropy alloys, (CoCrFeNiNb0.25Ta0.20; CoCrFeNiTa0.4;CoCrFeNiTa0.75;CoCrFeNiTa0.25Hf0.25; Co2MoxNi2VWx) by using Phy-X/PSD software. XCom was also performed to obtain the mass attenuation coefficients of the alloys, and a good agreement was obtained. It was concluded that Co2MoxNi2VWx has the most shielding property while CoCrFeNiNb0.25Ta0.20 shows the least shielding feature among the alloys.
