Mechanisms and kinetics of liquid silicon oxidation
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:145, Doctoral thesis, 2013)The formation of silica fume when liquid metal is in contact with air during refining of metallurgical grade silicon leads to a direct loss of silicon. Apart from this yield loss the associated fume may be harmful to the ... -
Mechanisms for texture in BaTiO3 thin films from aqueous chemical solution deposition
(Journal article; Peer reviewed, 2020)The prototype piezoelectric material BaTiO3 is widely used in e.g., capacitators. Chemical solution deposition (CSD) of BaTiO3 films is a simple and environmentally friendly processing route, but insight in the crystallization ... -
Mechanisms of graphite crucible degradation in contact with Si–Al melts at high temperatures and vacuum conditions
(Journal article; Peer reviewed, 2019)Graphite is a common refractory material for processing high purity silicon; however, it cannot be applied for holding Si–Al melts at high temperatures due to significant melt infiltration into the crucible. This research ... -
Mechanisms of inhibitor action - passivation and self-healing
(Chapter, 2020)In this chapter, we will briefly review the systematics of corrosion inhibitors and the classical mechanisms of action of corrosion inhibitors, the latter with an emphasis on inhibitors interacting with the material surface. ... -
Mechanistic investigation of the pretreatment of AA6060 with varying Ni and Cu content
(Master thesis, 2022)Aluminium er et allsidig materiale på grunn av metallets høye styrke-til-vekt-forhold, duktilitet og gode korrosjonsbestandighet. Økt bruk av resirkulert aluminium krever at det resirkulerte produktet oppnår de samme ... -
Mechanistic studies of the desmutting of AA6060 Aluminium Alloy
(Master thesis, 2023)Resirkulering av aluminium er en viktig prosess for å redusere det globale energiforbruket og for økt bærekraft. Imidlertid kan resirkulert aluminium basert på forbrukeravfall inneholde uønskede urenheter og forurensninger ... -
Medieval copper mining and smelting in Central Norway
(Chapter, 2019)In Norway, copper was used in alloys from the Bronze Age onwards, but domestic copper mining and smelting has not been recognized before the Late Middle Ages. A copper smelter found in Meråker Municipality in Central Norway ... -
Memristive TiO2: Synthesis, Technologies, and Applications
(Peer reviewed; Journal article, 2020)Titanium dioxide (TiO2) is one of the most widely used materials in resistive switching applications, including random-access memory, neuromorphic computing, biohybrid interfaces, and sensors. Most of these applications ... -
Meniscus Dynamics in Aluminium Extrusion Ingot Casting
(Dr. ingeniøravhandling, 0809-103X; 2002:57, Doctoral thesis, 2002)In the modern process of continuous Direct Chill (DC) hot top casting of aluminium extrusion ingot with gas slip, poor surface quality of the cast ingot can still be a problem. In the worst cases pronounced surface wrinkling ... -
Mesophase Transitions in [(C2H5)4N][FeBrCl3] and [(CH3)4N][FeBrCl3] Ferroic Plastic Crystals
(Peer reviewed; Journal article, 2022)Plastic crystals are supramolecular materials that possess a unique high entropy mesophase at elevated temperatures, where a long-range structural symmetry coexists with a local molecular orientational disorder. The ... -
Mesoscale Modeling of Dendritic Growth During Directional Solidification of Aluminium Alloys
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:13, Doctoral thesis, 2011)The development of materials based on metallic alloys with specific properties requires controlled solidification processes. Indeed, materials properties depend strongly on the microstructure. In the past few decades ... -
Metal and Slag Extraction from Different Zones of a Submerged Arc Furnace with Non-uniform Porous Bed Using CFD
