1. Iron Pieces from The Copper Wreck : An archaeometallurgical analysis of iron bars, billets and osmund iron found in Gdansk, Poland
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : The topic of osmund iron is of great interest in both historical and metallurgical perspective. Between the 14th and the 17th century osmund iron was exported extensively from Sweden but it has been difficult to characterize and confirm what exactly osmund iron is. LÄS MER
2. Effect of ash on catalytic activity for passive regeneration of catalytic diesel particulate filter : Evaluation of ash deposition by laboratory ageing
Master-uppsats, KTH/KemiteknikSammanfattning : Askackumulering i dieselpartikelfilter är ett välkänt problem som resulterar i ett förhöjt mottryck och påverkad prestanda hos fordonet. Däremot ges sällan uppmärksamhet åt filtrets katalytiska aktivitet och hur det påverkas vid förekomst av avgasföroreningar. LÄS MER
3. Precipitation behavior of the super austenitic stainless steel SANICRO® 35 and the effect on impact toughness and pitting corrosion resistance
Master-uppsats, KTH/MaterialvetenskapSammanfattning : This research extended the knowledge of the solid phase transformation and the resulting influence on impact toughness and pitting corrosion resistance in super austenitic stainless steel (SASS) SANICRO® 35. A time-temperature-transformation diagram (TTT diagram) was assembled by performing isothermal heat treatments in the temperature range of 650-1050 °C for different periods of time, ranging from 5 min to 500 min.

4. Critical elements scavenged by secondary gypsum and HFO : Determined by sequential extraction combined with mineralogical studies
Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknikSammanfattning : The demand for metals is great for the purpose of developing green technologies, and EU has listed 30 metals and minerals that are of critical importance for the maintenance and evolving of today’s society, so called critical materials. However, mining of raw materials generates mine waste which can have adverse effect on human health, ecosystems, and surrounding areas. LÄS MER
5. Evaluation of different non-metallic inclusions in steel chips by using electrolytic extraction : Evaluation of a methodology for electrolytic extraction and scanning electron microscopy - energy dispersive spectroscopy (SEM-EDS) analysis
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : Analysing non-metallic inclusions (NMI) by conventional microscopy is prone to errors. Better imaging can be achieved by using electrolytic extraction (EE) to effectively dissolve the metal matrix, freeing the inclusions so that they can be collected on a filter. LÄS MER
