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

    Detta är en avhandling från Stockholm : KTH

    Författare :Peter Wilberforce Olupot; KTH.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical porcelain; glaze; characterisation; multite; quartz; Uganda; TECHNOLOGY Materials science; TEKNIKVETENSKAP 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.

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

    Detta är en avhandling från Trollhättan : University West

    Författare :Arbab Rehan; Högskolan Väst.; [2017]
    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

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

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Cecilia Larsson; Linköpings universitet.; Linköpings universitet.; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

  4. 4. Microstructural, Mechanical and Tribological Characterisation of CVD and PVD Coatings for Metal Cutting Applications

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mikael Fallqvist; Uppsala universitet.; Högskolan Dalarna.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials; Tribology; Friction; Wear; Coatings; CVD; PVD; Alumina; Metal cutting; Steel Forming and Surface Engineering; Stålformning och ytteknik;

    Sammanfattning : The present thesis focuses on characterisation of microstructure and the resulting mechanical and tribological properties of CVD and PVD coatings used in metal cutting applications. These thin and hard coatings are designed to improve the tribological performance of cutting tools which in metal cutting operations may result in improved cutting performance, lower energy consumption, lower production costs and lower impact on the environment.
