The subject of this work is to take into account the corrosion environment influence in actual methodology of low-cycle fatigue (LCF) assessment and prediction. The aim of this paper is to summarize the current status of the Czech proposal of corrosion fatigue assessment and prediction. The first project focused on base steel materials, which are used in primary circuit of WWER-440, started in 2010. The basic idea of Czech environmental fatigue correction factor has been introduced on international PVP conference in 2013. The new project linked to the previous one is focused on the additional area of welding joints. Theoretical base is completed by experimental verifications of proposed environmental correction factor. The subject of actually running theoretical-experimental program covers similar metal welds of austenitic stainless steel 08CH18N10T and results will be available in 2015. Moreover LCF tests in corrosion environment of dissimilar metal welds are under preparation. Experimental work is based on LCF strain-controlled tests in primary water environment of WWER-440.</div>","PeriodicalId":101041,"journal":{"name":"Procedia Materials Science","volume":"12 ","pages":"Pages 18-23"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.mspro.2016.03.004","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84123871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thermocalc calculations were used for prediction of the effect of copper additions on equilibrium phases in the temperature interval 450 – 850°C. Minor phase evolution was studied by using transmission electron microscopy. Hot rolling was accompanied by dissolution of copper rich sulfides. Slow cooling of coils after hot rolling resulted in precipitation of Fe3C along ferrite grain boundaries. Decarburization annealing after the 1st cold rolling was accompanied by dissolution of Fe3C, re-precipitation of fine Cu2S, (Mn,Cu)S and very intensive precipitation of nitrides (AlN and Si3N4). Slow laboratory heating after the 2nd cold rolling to the onset of primary recrystallization (620°C) did not cause precipitation of any other minor phase.

FeSO4.7H2O was used for synthesis of magnetically responsive TiO2. The non-magnetic and prepared magnetic materials were characterized by scanning electron microscopy and X-ray diffraction methods. The particle size and specific surface area were determined. A detailed study of the adsorption process performed using batch adsorption experiments was carried out with various concentrations of lead ions and contact time. A flame atomic absorption spectrometer was used for determination of Pb2+ ions concentration in solution. Adsorption process has been modeled by the Langmuir and Freundlich isotherms using linear and non-linear regression. The results showed that the adsorption of Pb2+ ions on the magnetic and non-magnetic TiO2 particles occurred in a monolayer. Presence of magnetic iron oxides particles on the surface of sorbents increased the adsorption rate, and increased the maximum amount of adsorbed Pb2+ ions per mass in comparison with adsorption on the non-magnetic TiO2 particles.
