1. Characterization of Cu-mineralized carbonate veins in the Alta-Kvænangen Tectonic Window, Norway
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : The Alta-Kvænangen Tectonic Window is part of a regional greenstone belt that formed around 2.3 Ga – 2.0 Ga. The Bergmark anticline in the area has gone through greenschist to amphibolite facies metamorphism and hosts Cu, Co and Au mineralizations in hydrothermal veins, albite felsite and chemical traps.

2. The effect of recycling and processing routes on recrystallization in a secondary 3xxx aluminium alloy
Master-uppsats, Jönköping University/JTH, Material och tillverkningSammanfattning : 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. LÄS MER
3. Petrography of impactites from the Dellen impact structure, Sweden
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Identification and characterization of shock-metamorphic features in hypervelocity impact craters is important for our understanding of how shock waves interact with geologic materials and how impact craters form, which in turn is essential to our understanding of what role impact cratering played in the development of our solar system. Of particular interest are accessory minerals like apatite, which contains various volatiles that can affect the atmosphere of a body, or magnetite whose magnetic properties constitute a remote sensing indicator which allows us to study and understand the internal structures of distant bodies.

4. Mapping and treatment optimization attempt of monocalcium phosphate monohydrate (MCPM) in bioceramic implant production
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskapSammanfattning : The in vitro production of ceramic implants used for cranial defect repair can be challenging and complex. In this thesis, a raw material in such a production has been mapped in order to optimize the production process. LÄS MER
5. Microstructural characterization of quench annealed duplex SAF 2507 utilizing EBSD
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskapSammanfattning : Producing large bars of duplex stainless steel free from precipitated embrittling phases isdifficult due to the many factors that influence precipitation. Research shows that intermetallicslike sigma and chi deteriorate principal material properties for the main application areas. LÄS MER
