  1. 11. Characterization of energy gases by ultrasound : theory and experiments

    Författare :Pär-Erik Martinsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : The long-term goal with the research presented in this thesis has been to develop an ultrasonic sensor capable of measuring the energy content of energy gases such as natural- and biogas. The energy content can be calculated if the concentration of each constituent of a gas mixture is known. LÄS MER

  3. 12. Study of precipitation in martensitic Fe-C-Cr alloys during tempering : Experiments and modelling

    Författare :Ziyong Hou; Joakim Odqvist; Andersson Jörgen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fe-C-Cr alloy; Microstructure; Precipitates; Tempering of martensite; Electron microscopy; Modelling.; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : Understanding the precipitation reaction is very important since precipitation hardening is one of the most effective strengthening mechanisms in metallic alloys. In martensitic steels, a tempering heat treatment is often performed. LÄS MER

  5. 14. Transverse anisotropy in softwoods : Modelling and experiments

    Författare :Carl S. Modén; Lars Berglund; Lennart Salmén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Softwood; Cellular solid; Anisotropy; Deformation mechanisms; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Transverse anisotropy is an important phenomenon of practical and scientific interest. Although the presence of ray tissue explains the high radial modulus in many hardwoods, experimental data in the literature shows that this is not the case for pine. LÄS MER
