  1. 1. CARVING STEEL

    University essay from Göteborgs universitet/Steneby - Institutionen för Konsthantverk och Design

    Author : Arttu Halkosaari; [2020-09-25]
    Keywords : Forging; Tactility; Touch; Plasma cutting; Blacksmith; Texture; Contrast;

    Abstract : This exam project will be a conclusion for a long working process which started a year and a half ago. During this time, I have developed my own way of working with a plasma cutter and use that with different forged forms to create sculptures with varying textures. READ MORE

  3. 2. Sample quality effects of laser cutting : An empirical study on the heat affected zone and the surface quality in laser cut samples

    University essay from KTH/Materialvetenskap; KTH/Materialvetenskap

    Author : Emma Bevin; Matilda Björklund; [2020]
    Keywords : Laser cutting; Laser cutting quality; Heat affected zone; Surface quality; Surface angularity; Laserskärning; Laserskärnings-kvalité; Värmepåverkad zon; Ytkvalité; Ytvinkel;

    Abstract : This study has been conducted with the aim to examine the extent of the heat affected zone in order to use laser cutting when making samples for tensile testing. When cutting with a laser the material absorbs heat energy from the laser beams which causes changes in the microstructure. READ MORE

  4. 3. High temperature tribological evaluation of a self-lubricating laser cladding with and without external solid lubricant

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Cecilia Nemeth; [2020]
    Keywords : high temperature tribology; hot metal forming of aluminium; self-lubricating laser cladding; external solid lubricant;

    Abstract : The purpose of the project work was to build knowledge of the tribological behaviour of self-lubricating laser cladding, with and without external solid lubricant during conditions relevant for hot metal forming of aluminium. The materials used during the project were plates coated with a Ni-based self-lubricating clad and a reference sample of work tool steel. READ MORE

  5. 4. Assessment of the environmental impacts, energy performance and economic aspects of various construction materials
