  1. 1. EBSD Investigation of High-Temperature Magnetite from Apatite-Iron-Oxide Deposits: Implications for the Formation of Giant Kiruna-Type Deposits

    University essay from Uppsala universitet/Mineralogi, petrologi och tektonik

    Author : Jens Henriksson; [2022]
    Keywords : Kiruna-type deposit; electron backscattered diffraction; crystal settling; Fe-O systematics; crystal alignment;

    Abstract : European iron production is to a large extent dependant on massive Kiruna type apatite-iron ore deposits. In this contribution, high-temperature magnetite samples from apatite-iron-oxide deposits are investigated by means of Electron Backscattered Diffraction. However, the origin of Kiruna-type deposits is still unresolved. READ MORE

  3. 2. Effect of carbon activity on microstructure evolution in WC-Ni cemented carbides

    University essay from KTH/Materialvetenskap

    Author : Olivia Danielsson; [2018]
    Keywords : Cemented carbides; Hard metal; WC-Ni; Tungsten carbide; Nickel binder; Grain coarsening; Grain growth; Carbon activity; Size distribution; EBSD; Electron backscattered diffraction;

    Abstract : The aim of this work was to systematically study how the microstructure evolution is affected by the carbon activity in WC-Ni cemented carbides. Seven WC-9.59at%Ni alloys with different carbon activity were sintered at 1500 °C. READ MORE

  4. 3. Experimental Methodologies for Analyzing Austenite Recrystallization in Martensitic Tool Steels

    University essay from KTH/Materialvetenskap

    Author : Robin Nilsson; [2015]
    Keywords : Tool steels; Recrystallization; Prior austenite grain boundaries; Martensite; EBSD; Chemical etching; Thermal etching;

    Abstract : Revealing the prior austenite grain boundaries from a martensitic structure is well known to be very difficult and dependent on the chemical composition and the thermomechanical processing of the steel. In the present study, four different chemical etching reagents and additional thermal etching have been conducted for thermomechanical simulated tool steels Orvar Supreme and Stavax ESR. READ MORE
