  1. 1. Jämförelse av torr bearbetning och minimalsmörjningseffekter på fräsning av austenitiskt rostfritt stål

    M1-uppsats, Högskolan i Gävle/Maskinteknik

    Författare :Adam Norell; Darav Hajo; [2023]
    Nyckelord :MQL; milling; stainless steel; tool wear; MQL; fräsning; rostfritt stål; verktygsförslitning;

    Sammanfattning : Fräsning och annan intermittent skärande bearbetning ger upphov till termisk utmattning av skärverktyg. Problemet med termiska sprickor blir större vid bearbetning av värmehållfasta material som austenitiskt rostfritt stål eftersom värmeväxlingarna i skärverktyget blir mer extrema. LÄS MER

  3. 2. Gate oxide characterization of 4H-SiC MOS capacitors : A study of the effects of electrical stress on the flat-band voltage of n-type substrate 4H-SiC MOS capacitors

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Sotirios Maslougkas; [2021]
    Nyckelord :Silicon carbide; Gate oxide; Oxide characterization; MOS devices; Semiconductor- insulator interface; Kiselkarbid; Gate-oxid; Oxidkarakterisering; MOS-teknologi; halvledar-isolatorgränssnitt;

    Sammanfattning : Silicon is the main material used in electronics. The evolution of power electronics and the need for more power efficient semiconductor devices led silicon to its limits. Silicon carbide is a promising material for electronic applications with a wide band-gap, high critical electric field, high thermal conductivity and saturation velocity. LÄS MER

  4. 3. Understanding Effects of Isothermal Heat Treatments on Microstructure of LMD-w Titanium Alloy (Ti-6242) : On solution heat treated microstructure

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)
