Comparative Gamma and Neutron Shielding Performance of High-Entropy and Shape Memory Alloys: A Data-Driven Analysis

Description

High-entropy alloys (HEAs) and shape memory alloys (SMAs) have attracted significant interest for nuclear, aerospace, and medical applications due to their structural robustness. But their radiation shielding performance has yet to be evaluated in a direct, head-to-head comparison. In this study, the gamma-ray and fast-neutron attenuation properties of 59 alloys (30 HEAs and 29 SMAs) were evaluated against five standard reference materials across photon energies ranging from 0.015 to 15 MeV and a (_^235)"U" Watt fission neutron spectrum.
