1. Theoretical investigation of α-iron chromium carbide (α-Fe/Cr7C3) interfaces
Master-uppsats, Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)Sammanfattning : This master thesis presents a theoretical investigation of the energy and stability of interfaces in iron-carbide compounds, specifically focusing on the α-Fe/Cr7C3 system. The study aims to fill the gap in knowledge regarding the surface energetics of these interfaces using Density Functional Theory (DFT). LÄS MER
2. Investigation of the Cr solubility in the MC phase where M = Ti, Ta
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi; Uppsala universitet/Oorganisk kemiSammanfattning : In this work the chromium solubility in MC, and M in Cr3C2 and Cr7C3 carbides in the Ti-Cr-C and Ta-Cr-C system have been examined experimentally. Special attention is given to the cubic MC phase due to its frequent use in industrial cemented carbides. LÄS MER
3. Effects of tempering on corrosion properties of high nitrogen alloyed tooling steels in pyrolysis oil
Master-uppsats, KTH/KorrosionsläraSammanfattning : Nowdays biofuels are becoming a good alternative for petroleum fuels due to environmental issues like high carbon dioxide emission and increasing vehicles population, together with the high price and fast depletion of petroleum oils. This project aims to investigate the corrosive effects of wood Pyrolysis oil on a special grade of nitrogen alloyed tooling steels to be used for injector nozzles in Diesel engines, where high stress and strain encounter high acidity and corrosivity of the Pyrolysis oil and cause breakdown over short periods.
