  3. 2. Creativity in Design for Additive Manufacturing

    Författare :Angelica Lindwall; Anna Rönnbäck Öhrwall; Vinit Parida; Åsa Wikberg-Nilsson; Serena Graziosi; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DfAM; Creativity in Design; AM; Produktinnovation; Product Innovation;

    Sammanfattning : Additive Manufacturing (AM) brings opportunities to create designs with complex geometries that would be impossible or very difficult to produce using conventional manufacturing technologies. While AM is widely seen as a means to increase the creativity of designers and thus innovation within organisations, there is a lack of understanding of how designers can manage their creativity while working with Design for Additive Manufacturing (DfAM).

  4. 3. JNK/c-Jun Signaling and Peripheral Nerve Regeneration

    Författare :Charlotta Lindwall; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neuropsykologi; neurofysiologi; neurophysiology; Neurologi; neuropsychology; Neurology; Djurfysiologi; Animal physiology; JNK; signal transduction; nerve regeneration;

    Sammanfattning : The events associated with axonal injury in the peripheral nervous system (PNS) have been described in detail. However, the molecular mechanisms underlying the regenerative response, or neuronal cell death, following axonal injury are poorly understood. LÄS MER

  5. 4. Multicomponent diffusional reactions in tool steels : Experiment and Theory

    Författare :Greta Lindwall; Malin Selleby; Karin Frisk; John Ågren; Carelyn Campbell; KTH; []
    Nyckelord :hot-work tool steel; precipitation hardening; DICTRA; coarsening; mobilities; CALPHAD; cobalt; PM tool stees; nitrogen; compound materials;

    Sammanfattning : Many phenomena determining the microstructure of a tool steel and consequently the properties of the material, are governed by multicomponent diffusion. The diffusion driven reactions that take place during, for example, tempering of a hot-work tool steel or when the microstructure develops during hot isostatic pressing of cold-work tool steel, are dependent on the types and amounts of alloying elements.

  7. 5. Modelling of Bulk Metallic Glass formation in Powder Bed Fusion

    Författare :Johan Lindwall; Andreas Lundbäck; Mattias Unosson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Sammanfattning : This thesis discusses a model for simulation of the Powder Bed Fusion (PBF) process of metallic powder with the capability to become amorphous. The temperature field in the PBF process is predicted by a three-dimensional thermal finite element model in three dimensions using a layer-by-layer approach, meaning that the scanning strategy of the moving laser spot is consolidated into a single heat source acting on the entire layer momentarily.
