  1. 16. Influence of hydrogen and carbides on high temperature cracking in cast Inconel

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Gunnar Dufwa; [2022]
    Keywords : Hydrogen embrittlement; carbide; finite element method; dislocation dynamics;

    Abstract : Hydrogen embrittlement is a well-known source of cracking in metallic mechanical elements. This work studies the influence of hydrogen and carbides on the crack formation in a castnickel-alloy-component in a selective catalytic reduction system. READ MORE

  3. 17. Characterisation of GaN HEMTs on Different Substrates for Power Electronics Applications

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Hithiksha Krishna Murthy; [2022]
    Keywords : Gallium nitrate; High Mobility Electron Transistor; Silicon carbide; Silicon; Sapphire; substrates; power electronics;

    Abstract : GaN-based High Electron Mobility Transistors (HEMT) are appealing because of their large breakdown field, high saturation velocity, and superior thermal conductivity. They work at high temperature without much degradation. HEMTs have a few drawbacks despite many positives. The cost of developing GaN HEMTs on a native substrate is high. READ MORE

  4. 18. Investigation of robustness of a SiC MOMS pressure sensor in high pressure/temperature operation conditions

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Monika Sieczka; [2022]
    Keywords : ;

    Abstract : Rigorous environmental policies and the need for higher fuel economy continuously demand new innovations in the combustion process of automotive engines. Consequently, there is an increasing necessity for active monitoring of the combustion event, and therefore, microsystems have started coming into play. READ MORE

  5. 19. Efficiency Comparison between Two-Level and T-Type Inverter for 800 V Automotive Application

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Rishabh Jain; [2022]
    Keywords : Electric Vehicles; Efficiency Comparison; Loss Calculation; SiC MOSFET; T-Type Inverter; Three-level Inverter; Two-level Inverter; Inverter i två nivåer; inverter av T-typ; inverter i tre nivåer; SiC MOSFET; förlustberäkning; verkningsgradsjämförelse; elfordon;

    Abstract : The falling cost of batteries, along with an increasing need to cut emissions, has spurred significant interest in the electrification of vehicles. In addition, as semiconductor devices have evolved, the research for electric vehicles with higher battery voltage has increased. READ MORE

  6. 20. Evaluation of a novel method to investigate diffusion between copper-zinc alloys and cemented carbides

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : André Larsson; [2022]
    Keywords : Diffusion; Brass; Copper alloys; Copper zinc alloys; Wear; Cemented carbide; Diffusion couple;

    Abstract : When slow wear mechanisms are studied it is important to examine slower processes, such as diffusion. Such processes can have a significant impact over time and can cause other phases to form, which can have a large effect on the wear. READ MORE
