21. Characterization of phases in Argon Oxygen Decarburization slag
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : Slag is an important part of steelmaking with the AOD (Argon Oxygen Decarburization) process. In this work the focus was on developing a methodology for characterizing phases in slagsamples obtained after decarburization, reduction and desulphurization. LÄS MER
22. Recovery of Cobalt and Copper from Zambia Slag via Sulphidisation with Gypsum
Master-uppsats, KTH/MaterialvetenskapSammanfattning : The main objective of this research was to recover copper and cobalt from slags coming from copper processing on the Copperbelt province of Zambia. Pyrometallurgical processing of copper sulphide concentrate generates huge tonnes of slag wastes. LÄS MER
23. Receptoptimering av betong
Uppsats för yrkesexamina på grundnivå, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Betong står i dagsläget för ca 5% av världens CO2 utsläpp. Det är ett av det vanligaste och mest tillämpbara byggmaterial som existerar, att minska användningen av det på en stor skala är ej realistiskt då det inte finns någon rimlig ersättning till det.

24. Life and fracture in very high cycle fatigue of a high strength steel
Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Sammanfattning : Classical fatigue models teach that there is an intrinsic fatigue limit for steels, representing a level of stress that is too low for regular crack growth where every cyclic load propagates a fatigue crack through the material. Modern application with extreme lifetimes has shown that fatigue will still take place in steels with stress levels well below the expected fatigue limit. LÄS MER
25. Metallurgical analysis of some osmund iron from Sweden and Estonia : A short historical review of medieval iron production and export
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : During the Middle Ages, Sweden was a coveted exporter of high-quality iron in Europe. Bloomery furnaces could have produced osmund iron. However, most osmund iron was produced in blast furnaces. The iron was then treated in the finery process and cut into pieces. LÄS MER
