Characterization of Extruded Aluminium Alloys from Ram Extrusion and Screw Extrusion
(Master thesis, 2020)I denne oppgaven ble skruekstrudering sammenlignet med konvensjonell pressekstrudering for tre 6xxx legeringer. Effekten av ekstrudering og påfølgende varmebehandling ble undersøkt ved optisk mikroskopi, hardhetstesting ... -
Characterization of Flooring Composites
(Master thesis, 2017)The possibility of reinforcing high-pressure laminates with particles of yttria-stabilized zirconia has been investigated. The particles were embedded in a matrix of melamine formaldehyde resin, and several parameters, ... -
Characterization of Iron Bearing Particles in Relation to Fir-Tree Structure in Al-Mg Alloys
(Master thesis, 2018)Fir-tree structure is a well-known problem related to DC cast AA1xxx and AA5xxx alloys. During DC casting different iron bearing particles, e.g. AlmFe, Al3Fe and Al6Fe, are formed. A change of the dominating iron bearing ... -
Characterization of precipitates at maximum hardness and overaged conditions in Al-Mg-Si alloys
(Master thesis, 2011)A study of the influence of artificial ageing temperature on the precipitation behaviour in three distinct direct chill casted and extruded Al-Mg-Si alloys has been carried out. The total amount of alloying elements is ... -
Characterization of Screw Extruded Rapid Solidified AA6061
(Master thesis, 2014)By using rapid solidified aluminium as feedstock and a novel extrusion method, i.e. screw extrusion, it is possible to extrude aluminium continuously. Due to rapid solidification, the base material can have small grain ... -
Characterization of Structure and Optical Properties of Diatoms for improved Solar Cell Efficiency
