Abstract

In this study, the effect of Y₂O₃ contribution and γ-irradiation on the elastic properties of pure Al2024 and Al2024/Y₂O₃ composites was precisely investigated with the help of determined density and ultrasonic wave velocities. Ultrasonic longitudinal and shear wave velocity measurements of the samples were performed at room temperature using the ultrasonic pulse-echo method at 20 and 5 MHz frequencies, respectively. X-ray diffraction analysis and scanning electron microscopy examined the microstructural properties and phase characterizations of metal matrix composite (MMC) samples. A gamma cell type ⁶⁰Co source was used to irradiate MMC samples in the air at room temperature. The absorbed dose rate was measured to be approximately 1.5 kGy/h, and the total delivered dose was 50 kGy. According to the findings obtained from the research, the contribution of Y₂O₃ to pure Al 2024 at 0.5, 1, and 5 wt% ratios and exposure to gamma rays of 50 kGy caused a decrease in V_L, L, K, and μ values and a significant increase in ρ, V_S, G, HV, H, and E values. The highest Young's modulus values compared with pure Al2024 were obtained in both unirradiated and irradiated Al2024/0.5Y₂O₃ composites.

利用超声波法研究伽马射线和 Y2O3 对 Al2024 复合材料弹性性能的影响

在本研究中，借助测定的密度和超声波速度，精确研究了 Y2O3 掺杂和 γ 辐照对纯 Al2024 和 Al2024/Y2O3 复合材料弹性性能的影响。样品的超声纵波和剪切波速度测量是在室温下使用超声脉冲回波法进行的，频率分别为 20 MHz 和 5 MHz。X 射线衍射分析和扫描电子显微镜检查了金属基复合材料（MMC）样品的微观结构特性和相特征。在室温下，使用伽马电池式 60Co 源对空气中的 MMC 样品进行辐照。吸收剂量率约为 1.5 kGy/h，总剂量为 50 kGy。研究结果表明，纯铝 2024 中 Y2O3 的比例为 0.5、1 和 5 wt%，暴露在 50 kGy 伽马射线下会导致 VL、L、K 和 μ 值降低，ρ、VS、G、HV、H 和 E 值显著增加。与纯 Al2024 相比，未辐照和辐照 Al2024/0.5Y2O3 复合材料的杨氏模量值最高。

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.
