摘要

随着高辐射应用的增加,必须采取措施尽量减少辐射的不良影响。对于能够在高温下使用的材料的开发有很大的需求,特别是在核工业中。高温合金具有可以满足这一目的的特性。为了实现这一目标,在研究中生产了新的co基和ni基超级合金。Co基合金选用Ni、Fe、Mo、Cr、Nb、Ti、Al、Co、Ta和W, Ni基合金选用Ni、Fe、Cr、Nb、Ti、Al、Co和B。研究的目标是获得具有更好屏蔽性能和优越性能的新材料。对此,辐射防护参数;利用Phy-X/PSD程序计算了合金的线性衰减系数、质量衰减系数、有效原子序数、半值层、平均自由程、有效电导率、有效电子数、暴露和能量吸收积累因子、原子和电子截面以及快中子衰减截面。利用EPR、XRD和EDS-SEM等光谱技术对结果进行了评价。可以看出,W、Ta和Mo的含量由于具有高密度和高原子序数的特点,提高了合金的辐射衰减效率。快中子衰减能力受Ni、Ta、Mn和Mo含量的影响。结果表明,新制备的超级合金在核反应堆等高温应用中具有良好的辐射屏蔽性能。

Radiation Shielding and Spectroscopic Investigations of Newly Produced Co and Ni Based Super Alloys

Radiation Shielding and Spectroscopic Investigations of Newly Produced Co and Ni Based Super Alloys

With the rise in applications involving high-radiation exposure, it is imperative to implement measures to minimise the adverse effects of radiation. There is a great need for material development that can be used at high temperatures, especially in the nuclear industry. Superalloys have properties that can serve this purpose. In order to achieve this objective, new Co-based and Ni-based super alloys were produced in the study. Ni, Fe, Mo, Cr, Nb, Ti, Al, Co, Ta and W were selected for developing Co-based alloys, and Ni, Fe, Cr, Nb, Ti, Al, Co and B were selected for Ni-based alloy. The goal of the study is to obtain new materials which have better shielding performances with superior properties. In this regard, the radiation protection parameters; linear attenuation coefficients, mass attenuation coefficients, effective atomic number, half-value layer, mean free path, effective conductivity, effective electron number, exposure and energy absorption buildup factors, atomic and electron cross sections, and fast neutron attenuation cross-sections of the alloys were performed by Phy-X/PSD code. Further, EPR, XRD and EDS-SEM spectroscopic techniques were used and the results were appraised within this context. It can be noted that the content of W, Ta and Mo, due to the features of high density and high atomic number, improves the radiation attenuation efficiency of the alloys. It is also seen that the fast neutron attenuation ability is affected by Ni, Ta, Mn and Mo contents. It was concluded that the newly fabricated super alloys can be evaluated as good radiation shields in high temperature applications such as nuclear reactors.
