  2. 1. Laser welding and cladding : the effects of defects on fatigue behaviour

    Author : Md. Minhaj Alam; Stewart Williams; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Abstract : The thesis focuses on weld defects in laser processed materials (for laser welding, laser hybrid arc welding and laser cladding) and their effect on the fatigue life of components. Component properties were studied with particular emphasis on the macro and micro surface geometry, weld defects and clad defects. READ MORE

  4. 2. Use of EBSD Technique as a Means to Investigate the Microstructure of Engineering Materials

    Author : Muhammad Umar Farooq; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser cladding; coronary stents.; strain induced phase transformation; EBSD; oligocrystalline structures; WC-Co;

    Abstract : AbstractMaterials Science and Engineering has the aim to design or engineer the structure of a material to produce a predetermined set of properties. To be able to understand and predict the properties and observable characteristics of engineering materials, it is therefore necessary to understand their microstructure. READ MORE

  5. 3. Laser cladded steel - microstructures and mechanical properties of relevance for railway applications

    Author : Simon Niederhauser; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fe-Cr alloy; Carbon Steel; Microstructure; Internal Stresses; HAZ; Laser Cladding; Co-Cr alloy; Cracking Behaviour; Mechanical Properties; Low Cycle Fatigue;

    Abstract : Owing to increased requirements like increased axle load for railway wheels and rails, new material have to be employed. However, these requirements are mostly surface related, which makes it appropriate to change only the surface layer while keeping the bulk unchanged. READ MORE

  6. 4. Combination of heating and preservative impregnation of wood for outdoor exposure

    Author : Ekaterina Sidorova; Magdalena Kutnik; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

    Abstract : The research is presented as a composite thesis containing a theoretical explanatory review based on four scientific articles. The thesis covers the investigation of wood modification methods, which in the future could possibly be developed further to enhance the performance of wood products in an efficient and economical way.

  7. 5. Self-Lubricating Laser Claddings in the Context of Hot Metal Forming

    Author : Hector Torres; Braham Prakash; Manuel Rodriquez Ripoll; Paul Mayrhofer; Tomasz Liskiewicz; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; High Temperature; Laser Claddings; Self-Lubricating; Hot Stamping; Machine Elements; Maskinelement;

    Abstract : Laser cladding is a coating technique with significant advantages like the high quality of the resulting layers, their excellent metallurgical bonding to the substrate or the possibility to repair/rework high-value mechanical components. In recent years, the incorporation of solid lubricants to the base powder in order to produce self-lubricating claddings has been shown in the literature to be possible, with several of the described coatings being able to operate at high temperatures with low friction and wear.
