Effect of Alloying Oxides Y2O3 and ZrO2 on the Microstructure of Austenitic Steel 18Cr10NiTi

Nanomaterials are materials of new generation with unique characteristics which are not characteristic for other materials. Nanofilms, nanoprocessors, nanorobots – the more well known technologies, but demands of modern industry, electronic industry, power industry dictate the development of nanomaterials in higher scales. The use of nanomaterials is very promising direction in nuclear power. Conditions of operation of structural materials in nuclear reactors, namely, high temperature (higher 300°C for thermal reactors and higher 600°C for fast reactors) which together with high density of neutrons (~1021-1022 neutrons/cm-2) cause the degradation of initial physical-chemical characteristics and the significant dimension changes. These factors influence considerably on safe and long-term operation period of reactor
