    Keywords : geology; geochemistry; spinel; Cr-spinel; chromite; SEM; scanning electron microscope; electron microprobe; EMP; electron probe microanalyzer; EPMA; electron micro probe analyzer; EMPA; petrogenetic indicator; microscopy; alteration; Franklinian Mobile Belt; Kulutingwak Formation; Clements Markham fold belt; Pearya; Paleozoic; suprasubduction zone; SSZ; island arc; IA; Arctic Canadian Archipelago; Ellesmere Island; Canada; 2017 Circum-Arctic Structural Events Expedition 19; Memorial University of Newfoundland; geologi; geokemi; spinell; Cr-spinell; kromit; SEM; svepeletronmikroskopi; elektronmikrosondanalys; EMP; EPMA; EMPA; petrogenetisk indikator; mikroskopi; Franklinian Mobile Belt; Kulutingwak-formationen; Clements Markham fold belt; Pearya; Paleozoikum; suprasubduktionszon; SSZ; öbåge; IA; Kanadas arktiska öar; Ellesmereön; Kanada; 2017 Circum-Arctic Structural Events Expedition 19; Memorial University of Newfoundland;

    Abstract : The chemical compositions of Cr-spinel extracted from mafic and ultramafic rocks collected on Ellesmere Island in the Arctic Canadian Archipelago were obtained through electron microprobe analyses. The extensively altered rocks are sampled from rock units in the Franklinian MobileBelt, which is representative of a Paleozoic tectonically active oceanic regime of which little is presently known.

  2. 2. The Production of Samarium-Cobalt Nanoparticles Using a Spark Discharge Generator

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Timothy Lewis; [2019]
    Keywords : Physics and Astronomy;

    Abstract : In this project I attempt to press custom electrodes from Sm and Co powder using two different pressing tools. I investigate if custom electrodes can generate nanoparticles with tailored properties using a spark discharge generator (SDG). READ MORE

  3. 3. Correlation of microstructural damage to functional properties of irradiated carbon fibre based composites used in neutron chopper discs

    University essay from Lunds universitet/Hållfasthetslära

    Author : Hanna Molin; [2019]
    Keywords : radiation; epoxy; carbon fiber; CFRP; ESS; European Spallation Source; Technology and Engineering;

    Abstract : Understanding material behaviour has in the past enabled human development and will continue to characterize the various stages of our future development. The use of neutrons will greatly affect several research areas, such as sustainable energy production and cancer research, due to their interaction with nuclei. READ MORE

  4. 4. Optimization of Rare Earth Metals (REM) addition in high temperature stainless steel grade 253MA.

    University essay from KTH/Materialvetenskap

    Author : Bharath Vasudev Rangavittal; [2019]
    Keywords : REM addition; non-metallic inclusion; oxidation; austenitic; optimization;

    Abstract : The focus of this thesis work is to optimize rare earth metal (REM) addition in Therma 253MA, an austenitic stainless-steel grade in order to get a good trade-off between oxidation resistance property and the amount of big REM inclusions formed. Big REM inclusions are detrimental to material properties and REM is required to be dissolved in the matrix for improving the oxidation resistance. READ MORE

  5. 5. Experimental and Theoretical Investigation of Selective Laser Melted Uddeholm Dievar ®

    University essay from KTH/Materialvetenskap; KTH/Materialvetenskap

    Author : Sanjin Pepić; Otto Ridemar; [2019]
    Keywords : Uddeholm Dievar®; Additive manufacturing; AM; Selective laser melting; SLM; Gas-atomization; Hot-work tool steel; Uddeholm Dievar®; Additiv tillverkning; AM; Selective laser melting; SLM; Gas- atomisering; Varmarbetsverktygsstål;

    Abstract : The main problem encountered in this thesis is the lack of research and knowledge of selective laser melted-printing with Uddeholm Dievar®. This absence of information could cause issues regarding quality and properties of the alloy as well as uncertainty regarding an appropriate heat treatment cycle. READ MORE
