Effect of Microstructure on the Performance of Corrosion Resistant Alloys
(Master thesis, 2015)Corrosion by pitting in aluminum alloys is a very complex process that can be affected by various factors such as chemical composition and microstructure of the alloys. The electrochemistry and distribution of second phases ... -
Impurities in Ilmenite: Magnesium
(Master thesis, 2015)The influence of Mg as main impurity in ilmenite during gaseous reduction with CO and H2 gas was studied in this work. This is of interest for the ilmenite pre-reduction step in the Tyssedal Process as where the impurities ... -
Inclusion Optimized Silicon for the Production of Silicones
(Master thesis, 2015)One of the challenges with silicones production is the accumulation of impurities from metallurgical grade silicon (MG-Si) in the reactor. Size, shape and density of the intermetallics affect the accumulation, and their ... -
Kinetics of the reaction between quartz and silicon carbide in different gas atmospheres
(Master thesis, 2015)This thesis examined the influence of different gas species in the kinetics of SiO2+SiC reaction. The quartz and silicon carbide were crushed to < 38µm, uniformly mixed together with weight ratio of 3:1 and pelletized into ... -
Metal loss comprehension - metal emulsions in ferromanganese slags
(Master thesis, 2015)Literature review was done on metal in slag emulsions, using the surface phenomena literature in metallurgy as well as the oil and water emulsion broader literature. Several phenomena were found that could extend to the ... -
Mn alloys production with the use of natural gas. - Understanding the kinetics of Mn alloy production
(Master thesis, 2015)This research intends to develop the necessary understanding regarding the reaction kinetics involved in the production of manganese ferroalloys. The main reactions of interest are as follows: MnO_((l) )+C_((s,l))=Mn_((l ... -
Numerical modelling of a Czochralski furnace with active cooling jacket - Optimization of quality and througput
(Master thesis, 2015)In the single crystal silicon Czochlarski process, pull rate has a great impact on its production. More and more people put their eyes on optimizing the structure of Cz furnace to increase the pull rate, but experiments ... -
The performance change of aluminum electrolysis in standard cryolite electrolyte with cathodic current density
(Master thesis, 2017)A series of experiments were performed to verify the effect of current density in current efficiency of aluminum electrolysis in molten salts. To avoid interference of other parameters, a special designed laboratory cell ...
