Austenitic stainless steel and the Zr-1%Nb alloy have been studied, which are used in the nuclear industry as structural materials. The following irradiation parameters have been applied: the accelerating voltage of 200 kV, pulse duration of 90 ns, and the energy density per pulse of 1.5 J/cm2. After irradiation, coatings of both Fe-Cr-Al and Al-Si-N systems have been deposited by magnetron sputtering. Then, both normal and accidental losses of coolant conditions for water-cooled nuclear reactors are simulated. Radiation damage was modeled using 400 keV protons with a current density of 0.667 μA/cm2and a fluence of 2.25∙1016 proton/cm2. The second modeling method was the hydrogenation of samples – 360 °C, pressure of 2 atm for 2 hours. After irradiating the coatings with protons or saturating them with hydrogen, high-temperature oxidation of the samples was carried out in air and steam at a temperature of 1000 °C for 180 seconds. Finally, the oxidized samples have been studied by scratch tests and subsequent investigations using scanning electron microscopy in order to understand the effect of the pre-treatment procedure.","PeriodicalId":156877,"journal":{"name":"8th International Congress on Energy Fluxes and Radiation Effects","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122694514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Proposed constitutive equation described the mechanical response of HCP titanium and zirconium alloys in a wide range of strain rates at the temperatures below temperature of phase transformation.

Plasma-solution synthesis has established itself as a simple and effective method for obtaining ultrafine materials with new properties. The formation of precipitation under the action of atmospheric pressure glow discharge on an iron and cobalt nitrates solution, which was the anode, was studied. It turned out that the rate of formation increases with an increase in the discharge current from 30 to 70 mA. In the course of work, the concentrations of nitrates were varied. The concentrations were chosen in such a way that the final product was stoichiometric Fe2O3·CoO. The result of the study of kinetic regularities indicates that the sedimentation of the solid phase from nitrate solutions occurs in two stages. The first is the precipitation of particles containing iron anions; the second capture is the precipitation of cobalt-containing particles.","PeriodicalId":156877,"journal":{"name":"8th International Congress on Energy Fluxes and Radiation Effects","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129740424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
