Abstract

It is shown by the example of hydrogen (in hydrides ZrH), helium (in pores after implantation), and nickel (in G-phase precipitates) that the application of electron energy-loss spectroscopy within the scanning transmission electron microscopy method makes it possible to analyze the distribution of different chemical elements in the microstructure of reactor materials. The advantages of electron energy-loss spectroscopy (in comparison with energy-dispersive spectroscopy) for studying irradiated materials and important experimental conditions of the formation of energy loss spectra are discussed.

电子能量损失谱在反应堆材料微观结构分析中的应用

摘要

氢（在氢化物 ZrH 中）、氦（在注入后的孔中）和镍（在G相沉淀物中）的例子表明，电子能量损失谱在扫描透射电子显微镜方法中的应用使其成为可能分析不同化学元素在反应器材料微观结构中的分布。讨论了电子能量损失光谱（与能量色散光谱相比）在研究辐照材料方面的优势以及形成能量损失光谱的重要实验条件。
