  5. 9. Novel Insights into the Oxidation of High Temperature Alloys - The Role of Environment, Microstructure and Reactive elements

    Författare :Nooshin Mortazavi Seyedeh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reactive elements; nitridation; High temperature materials; nitrides; alumina; hydrides; microstructure; chromia; oxidation;

    Sammanfattning : The properties of materials can be deteriorated, when they react with an environment at high temperature and form various types of corrosion products, such as oxides and nitrides. In order to perform successfully at elevated temperatures, all these materials are required to be protected by a slow-growing, continuous and adherent surface oxide layer. LÄS MER

  7. 10. High Temperature Oxidation and Chlorination of FeCrAl alloys

    Författare :Niklas Israelsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; KCl; pre-oxidation; FeCrAl; H2O; high-temperature corrosion; kinetics;

    Sammanfattning : AbstractThe constant strive for improved efficiency and lower-cost industrial processes often results in progressively higher temperatures and more aggressive environments. High- temperature corrosion is a well-known problem in biomass- and waste-fired boilers and is one of the obstacles to overcome in achieving a more sustainable society. LÄS MER
