| Summary: | Title screen In this work, we have investigated the defect structure of an E110 zirconium alloy after saturation with hydrogen by means of the layer-by-layer system analysis. A series of experiments were intended to create a hydride rim in zirconium alloy cladding tubes. To determine the distribution of a hydrogen gradient and the thickness of hydrides in zirconium alloy samples, a layer-by-layer positron spectroscopy system was developed. The results from the developed positron annihilation method are well consistent with the results from nanohardness indentation and glow discharge optical emission spectroscopy (GD-OES). We can draw a conclusion that the use of nickel-plating on the zirconium alloy surface increases the rate of hydrogen entering the surface, which produces a hydride rim with a thickness of about 150 µm on the outer surface of the E110 alloy. This work allowed us to develop a methodology for studying the defective structure of alloys in the field of nuclear energy Текстовый файл AM_Agreement |
