    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

  3. 2. Thermal Stability of Titanium and Niobium Stabilized Stainless Steel

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Oskar Darselius Berg; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This master thesis examined the microstructure after heat treatments in stainless steel, two conventional stainless steel (304 and 316) and two novel high temperature stainless steel. These stainless steels are for the use in high temperature heat exchangers for extended temperature range. LÄS MER

  4. 3. Microstructure investigations of WC-Co cemented carbide containing Eta-phase and Cr

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Sofia Tran; [2018]
    Nyckelord :Cemented carbide; Eta-phase; Chromium; Material characterization;

    Sammanfattning : Cemented carbide containing sub carbide phases, M6C and M12C, known as eta-phase, increases the lifetime milling cutters due to increased resistance to comb cracks. When milling, the inserts much sustain high temperatures, meaning edgeline toughness and thermal fatigue resistance are needed. LÄS MER

  5. 4. 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 kemi

    Författare :Anna Ehrenborg; [2016]
    Nyckelord :cubic carbides; Cr solubility;

    Sammanfattning : 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
