1. Beyond Breakaway Corrosion: Investigating the Secondary corrosion protection of Iron-based alloys
Sammanfattning : High temperature corrosion of metallic materials remains a major challenge for many in-dustrial applications. The challenges of high temperature corrosion are often addressed by using highly alloyed materials such as stainless steels or FeCrAl alloys. LÄS MER
2. High Temperature Corrosion of FeCrAl Alloys in Biomass- and Waste-fired Boilers - The Influence of Alloying Elements in Prediction and Mitigation of Corrosion in Harsh Environments
Sammanfattning : Combustion of biomass and waste for heat and power production is an alternative to fossil fuels and can be an important step towards a more sustainable future. The electrical efficiency of the fuel-to-energy conversion process is largely dependent on the steam parameters (temperature and pressure) of the combined heat and power (CHP) plants. LÄS MER
3. Microstructure and high temperature properties of Mo(Si,Al)2 - The effect of particle strengthening and alloying
Sammanfattning : High temperature heating processes within the steel industries result in significant emissions of CO2, primarily due to the combustion of fossil fuels. Electrification of these processes, such as through the implementation of resistive heating elements, holds great promise for reducing emissions. LÄS MER
4. A critical survey of the grain refining mechanisms of aluminium
Sammanfattning : In the present work, several possible interpretations of the grain refining mechanisms of aluminium castings after additions of titanium and boron are compared with the results of critical test experiments. The presence of B does not seem to affect the binary Al-Ti phase diagram close to the A1 comer, except for formation of boride phase. LÄS MER
5. Materials and Coatings for Superheater Tubes in Biomass- and Waste-fired Boilers
Sammanfattning : Combustion of biomass and waste fuels has strong potential as an alternative renewable energy source for meeting the increasing global energy demand, while reducing the net release of CO2 into the atmosphere. The combustion of biomass and waste releases flue gases that contain high amount of alkali salts and water vapour, which drive the corrosion of metallic boiler components. LÄS MER
