Press Form Hardening of Aluminium Alloys 7021 and 6082. A Feasibility Study.
(Master thesis, 2016)Aluminium alloys 6082.25 and 7021.50 were evaluated and compared as potential base materials for processing by press form hardening. Both extruded profiles and rolled sheets were assessed, however the rolled 7021 material ... -
Production of Silicomanganese from Comilog Ore - Reduction Behavior
(Master thesis, 2016)The reduction behavior of silicomanganese (SiMn) charges based on Comilog ore was investigated. The charges were heated up to to different temperatures by using a thermogravimetric graphite tube furnace. The weight loss ... -
Recrystallisation Behaviour in Extruded Profiles of Non-Dispersoid Containing Al-Mg-Si Alloys
(Master thesis, 2015)Hot extrusion of non-dispersoid containing aluminium alloys commonly ends with a fully or partially recrystallised grain structure. However, the recrystallisation mechanisms, whether static or dynamic (taking place during ... -
Screw Extrusion from various Binary Al-XMg Feed Materials - Effects of Heat Treatment on Microstructure
(Master thesis, 2016)Three direct chill (DC) cast aluminium-magnesium (Al-Mg) alloys, with 5, 8, and 10 wt% magnesium, have been used as base materials. These base materials were either rapidly solidified by melt spinning, or granulated by ... -
Solidification of Titanium Slags and Influence on Post Processing
(Master thesis, 2016)Ilmenite is a titanium-rich ore, and accounts for almost all the world's consumption of titanium bearing minerals. One of the main uses of titanium is as powdered TiO2, used extensively as whitening pigment. The first step ... -
Strain-Path Changes in Brass (Cu-20Zn)
(Master thesis, 2017)Metals are often exposed to multi-path loading in the forming process. Plastic deformed in more than one direction can have significant effects on microstructural evolution and mechanical behaviour. These mechanisms and ... -
Studie av andel deltaferritt og austenitt som funksjon av anløpingstemperatur med in-situ HT-XRD i S165M martensittisk rustfritt stål
(Master thesis, 2015)Denne oppgaven har som formål å avgjøre om bruk av in-situ høytemperatur røntgendiffraksjon kan brukes til å analysere utviklingen av austenitt og δ-ferritt i det martensittiske rustfrie stålet S165M, omtrent 16% krom, 5 ... -
Texture and Microstructure Evolution during Extrusion of AlMgSi-Alloys
(Master thesis, 2016)The main objective of this thesis is to contribute to a better understanding of the microstructure and texture evolution during extrusion of AlMgSi alloys. The textures and microstructures in AA6082 were analysed after ... -
The effect of carbon and boron carbide additions in pressure assisted sintered silicon carbide
(Master thesis, 2017)Silicon carbide is a highly covalent ceramic, so additives like carbon and boron must be present in order to obtain a dense material during sintering. The focus of this project is to investigate how the amount of carbon ... -
The Influence of Transient Change in Strain Rate on Subgrain Size During Deformation by Torsion of AA6063
(Master thesis, 2016)During hot extrusion a extrusion billet s cross section is reduced, altering the metals micro- structure. As the billet is passing through the extrusion die the strain rate and temperature increases, resulting in a with a ... -
The Oxygen Evolution Reaction at Iridium-Ruthenium Oxide Catalysts for PEM Water Electrolysis
(Master thesis, 2015)A sustainable method for hydrogen production can be achieved with PEM water electrolysers. These are considered important for the transition to a society based on renewable energy production as they can be coupled with ... -
Thermomechanical processing of an AA6082 - IF steel cold roll bonded composite material
(Master thesis, 2017)The work carried out in this thesis was conducted to investigate thermomechanical aspects of a steel-aluminum cold roll bonded material. The objective was to study different production parameters related to ageing of an ... -
Utmatting av AA6005 - Effekten av forskjellige tilstander
(Master thesis, 2016)The aim of this thesis is to investigate the effect of ageing, both natural and artificial, at room temperature on the fatigue properties of AA6005. Artificial ageing was done to reach a temper state of equal hardness on ...
