  2. 6. Interaction mechanisms of pulsed laser beams at different wavelengths with matter

    Author : Olga Yalukova; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Abstract : This thesis presents an investigation of the interaction mechanism involved in processing of different engineering materials using pulsed TEA CO2- and Nd:YAG lasers. Several methods were used. Digital Speckle Photography (DSP) or Speckle Correlation was used to detect micro-structural changes in the material surface during laser irradiation. READ MORE

  4. 7. Tailoring structure and morphology during additive manufacturing of metallic components

    Author : Jithin James Marattukalam; Björgvin Hjörvarsson; Ulf Jansson; Martin Sahlberg; Lars Nyborg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Selective laser melting; process parameters; scanning methodologies; AMLOYZR01; bulk metallic glass; 316L SS; grain orientation;

    Abstract : The work described in this thesis explores the use of laser process parameters to functionalize the material properties by the control of microstructure and optimization of morphology in components by selective laser melting. The microstructure in amorphous and crystalline metallic alloy systems is influenced by changing the laser power density and scanning strategies respectively. READ MORE

  5. 8. Local structure and composition : in additively manufactured bulk metallic glasses and composites

    Author : Inga Katharina Goetz; Jochen M. Schneider; Björgvin Hjörvarsson; Ulf Jansson; Maria Teresa Pérez Prado; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; additive manufacturing; bulk metallic glasses; nanoscale clustering; convective flow; laser nitriding; laser powder bed fusion; metallic glass - ceramic composites; oxygen impurities; mechanical properties; magnetic properties; viscosity; Fysik; Physics;

    Abstract : Additive manufacturing enables the production of complex multi-material geometries and bulk metallic glass parts beyond their critical casting thickness. The local modification of structure, composition, and properties is explored in this thesis with the aim to design novel composite materials and functional gradients. READ MORE

  6. 9. Compressive failure of glass fibre NCF composites

    Author : Claes Isaksson; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Compressive failure of polymer matrix compos ites is very much controlled by material heterogeneity (e.g. fibre waviness and gaps) and out-of-plane loadings (e.g. READ MORE

  7. 10. Manufacturing and Characterization of Filled Polymeric Systems

    Author : Henrik Oxfall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PS; hybrid composites; EBA; computer simulations; graphene; rheology; mould filling; graphite nanoplatelets; powder injection moulding; electrical conductivity; elongational flow; thermal properties; jetting;

    Abstract : The physical properties are changed if fillers are added to a polymeric material. In this work a highly filled model system for power injection moulding (PIM) and graphite nanoplatelet (GNP) based nanocomposites have been manufactured and characterized. READ MORE
