  3. 2. Sound quality evaluation of heavy-duty engines in free field conditions

    Författare :Md. Shafiquzzaman Kahn; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : Annoyance response to vehicle noise is commonly reported. The impact reduction measures must therefore be measured scientifically. A scientific system for describing and defining annoyance is therefore required. There is furthermore a need to reduce the annoying components of the sound of vehicles. LÄS MER

  4. 3. Atomic-scale investigation of interfacial structures in WC-Co at finite temperatures

    Författare :Erik Fransson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; complexions; phase diagrams; interfaces; force constants; cluster expansions; atomic-scale modeling; free energies; cemented carbides; WC--Co;

    Sammanfattning : WC-Co cemented carbides combine superb hardness with high toughness making them ideal for usage in high-speed machining of steels and in wear resistance tools. These excellent mechanical properties are to a large extent dependent on the microstructure and thus the interfacial properties of the material. LÄS MER
