De-Icing Coatings Based on Solar Illumination
(Master thesis, 2023)Avising av overflater er viktig for ulike strukturer i kaldt klima, som veier, høyspentlinjer, vindmøller eller i luftfartsindustrien. Målet med dette arbeidet er å undersøke fabrikasjonsprosessen og karakterisere fire ... -
Plasticity of solid solution Al-Mn and Al-Mn-Si alloys
(Journal article, 2024)The influence of Mn and Si on the mechanical properties of solid solution Al-Mn and Al-Mn-Si alloys have been studied at 4 K, 78 K, and 298 K. The solute strengthening potency of the yield strength increases with decreasing ... -
The microstructural origin of a hardness double-peak in an age-hardened EN-AW 6082
(Peer reviewed; Journal article, 2023)In this study, the origin of a double-peak during artificial aging of an EN-AW 6082 is analyzed with (S)TEM. The acquired TEM data is used as an input into a strength model by Holmedal [1] to explore the origin of the ... -
Pre-reduction of United Manganese of Kalahari Ore in CO/CO<inf>2</inf>, H<inf>2</inf>/H<inf>2</inf>O, and H<inf>2</inf> Atmospheres
(Peer reviewed; Journal article, 2023)The incorporation of hydrogen, which is a relatively unexplored reductant used during ferromanganese (FeMn) production, is an attractive approach to lessen atmospheric gaseous carbon release. The influence of hydrogen on ... -
A continuous multiphase model for liquid metal batteries
(Peer reviewed; Journal article, 2023)Liquid metal batteries (LMBs) are a promising candidate for large-scale stationary storage of renewably generated energy. Their Earth-abundant electrode materials and highly conductive molten salt electrolytes confer the ... -
Investigation of slag and condensate from the charge top in a FeSi75 furnace
(Chapter, 2023)Metallurgical silicon/ferrosilicon is produced industrially in submerged arc furnaces by carbothermic reduction of quartz. In addition to raw materials, oxide impurities are present in the furnace. Accumulated slag is ... -
