  4. 3. Characterization of Ceramic Raw Minerals in Uganda for Production of Electrical Porcelain Insulators

    Författare :Peter Wilberforce Olupot; Stefan Jonsson; Thomas Johansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical porcelain; glaze; characterisation; multite; quartz; Uganda; Materials science; Teknisk materialvetenskap;

    Sammanfattning : In this work an extended literature survey on ceramics and porcelains in particular, has been documented. Samples from two Ugandan deposits of each feldspar and quartz were characterised by means of X-ray diffraction, thermal analysis, chemical analysis and scanning electron microscopy and found to possess requisite properties for making electro porcelain insulators.

  5. 4. Microstructure and mechanical properties of a 5 wt.% Cr cold work tool steel : Influence of heat treatment procedure

    Författare :Arbab Rehan; Lars-Erik Svensson; Leif Karlsson; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cold work tool steel; Heat treatment; Microstructural characterisation; Mechanical properties; Retained austenite; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : The demand for Advanced High Strength Steel (AHSS) in the automotive industry is increasing day by day. It is mainly motivated by the fact that AHSS can be used as thin sheets while having high strengths. LÄS MER

  7. 5. Thermal residual stresses, hardness and microstructural characterisation of functionally graded WC-Co composites

    Författare :Cecilia Larsson; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Functionally graded materials (FGMs) incorporate gradual transitions in their microstructure and/or composition with distance. The gradients provide means to favourably engineer their thermomechanical properties by changing e.g., the local modulus, yield strength, state of residual stress etc. LÄS MER
