Abstract

This study explores the gamma-ray and neutron shielding properties and mechanical performance of eight Fe-based alloys with varying elemental compositions and densities. Different parameters such as mass attenuation coefficients, linear attenuation coefficients, half-value layer, tenth-value layer, mean free path, fast neutron removal cross-sections, transmission factors were analysed using PHITS and Phy-X/PSD codes. Moreover, elastic modulus values were calculated for each alloy sample. Our results reveal that the S9 alloy, with high density and tungsten contribution, exhibited superior shielding and mechanical properties, achieving the lowest TF, HVL, and TVL values. In contrast, the low-density S1 alloy performed weakest, reflecting its lighter elemental composition. Intermediate alloys like MAR-302 and Cupero-Nickel showed balanced performance, suitable for moderate shielding needs. Strong correlations between elemental compositions, particularly high-Z elements like tungsten and boron, and shielding efficiency were observed. It can be concluded that optimizing elemental composition and density is critical for designing alloys with enhanced multifunctional properties.

关键辐射应用铁基/含铁新型合金的弹性模量、核辐射透射性能

本研究探讨了不同元素组成和密度的8种铁基合金的γ射线和中子屏蔽性能和力学性能。利用PHITS和Phy-X/PSD编码分析了质量衰减系数、线性衰减系数、半值层、十值层、平均自由程、快中子去除截面、透射系数等参数。并计算了各合金试样的弹性模量。结果表明，高密度、高钨含量的S9合金具有较好的屏蔽性能和力学性能，具有较低的TF、HVL和TVL值。相比之下，低密度S1合金表现最弱，反映了其较轻的元素组成。中间合金如MAR-302和Cupero-Nickel表现出平衡的性能，适合中等屏蔽需求。元素组成，特别是高z元素，如钨和硼，与屏蔽效率之间存在很强的相关性。结果表明，优化元素组成和密度是提高合金多功能性能的关键。

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
