  1. 1. APPLICATION OF IN SITU Rb-Sr DATING AND GEOCHEMICAL INVESTIGATIONS ON A NEW, 1.52-1.56 GA. OLD PEGMATITE FIELD IN THE ARCHIPELAGO OFF GOTHENBURG, IDEFJORDEN TERRANE, WESTERN SWEDEN

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Laszlo Zorc; [2023-08-18]
    Keywords : ;

    Abstract : In this study, Rb-Sr geochronology was used to determine the crystallization/cooling ages of muscovites and biotites from mapped primitive barren and rare element pegmatites in the Stora-Le-Marstrand Formation in the southwestern archipelago of Gothenburg. The results indicate that primitive barrens can be linked to the DG2 deformation event that occurred 1. READ MORE

  3. 2. Commissioning of ITER heat rejection system for low load

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Elizaveta Yakovleva; [2023]
    Keywords : commissioning; ITER; fusion; control logic; cooling system; I C;

    Abstract : This project has commissioned the control logic of the Heat Rejection System (HRS) at ITER, the international fusion project. The HRS is a large system, including 10 cooling towers, 13 pumps, and pipes large enough for a water flow of several thousand kg/s. All of this will becontrolled with automatic control logic.

  4. 3. The effect of recycling and processing routes on recrystallization in a secondary 3xxx aluminium alloy

    University essay from Jönköping University/JTH, Material och tillverkning

    Author : Anton Rolseth; [2023]
    Keywords : Aluminium alloys; sheet metal forming; grain boundary segregation; recrystallization; Zener pinning; casting; rolling;

    Abstract : Aluminium alloys have the possibility to be infinitely recycled. By only generating 5% of the emissions compared to primary aluminium, great CO2 savings can be made. One of the issues in manufacturing components entirely from post-consumer scrap is the presence of trace elements and impurities. Such elements can be Fe, Cu, Cr, P and Pb. READ MORE

  5. 4. Effect of Trace Elements on the Particle Size of Magnesium Silicide in Aluminium Extrusion : The Use of Thermo-Calc and DICTRA in order to Produce Aluminium more Efficiently

    University essay from KTH/Materialvetenskap

    Author : Gustav Boustedt; Johan Alexander Valentin Nygren; Gustav Strandgård; [2023]
    Keywords : Thermo-Calc; DICTRA; simulations; EN AW 6082; extrusion; particle precipitation; Mg2Si; sustainable; trace elements; aluminium;

    Abstract : This project is a feasibility study for Hydro Extrusion Sweden AB, a company that produces extruded aluminium profiles. The main purpose of this project was to analyse the difference of Mg2Si particle sizes in aluminium alloys when varying parameters, such as cooling rate and composition, in aluminium extrusion, particularly the EN AW 6082 alloy.
