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 tektonikAbstract : 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

2. Effect of carbon activity on microstructure evolution in WC-Ni cemented carbides
University essay from KTH/MaterialvetenskapAbstract : 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

3. Experimental Methodologies for Analyzing Austenite Recrystallization in Martensitic Tool Steels
University essay from KTH/MaterialvetenskapAbstract : 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

4. Evaluation of the η (Eta) nitride with three laboratory melts
University essay from KTH/MaterialvetenskapAbstract : η (eta) nitride, Cr3Ni2SiN, is a precipitate found in high temperature austenitic stainless steel and is not yet included in Thermo-Calc steel database TCFE7. The aim of this thesis is to collect thermodynamic data to enable the addition of η nitride in the databases. READ MORE
