  1. 11. Investigations of Heavy Elements in Am and HgMn stars

    Författare :Linus Dolk; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HgMn stars; spectroscopy; heavy elements; Astronomi; Astronomy; Chemically peculiar stars; Am star; Fysicumarkivet A:2002:Dolk;

    Sammanfattning : The relationship between the HgMn and Am classes of chemically peculiar stars has been investigated primarily by observing abundances of heavy elements, including Pr, Nd, Hg, Tl and Bi. The main objective of the investigation has been to gather observational evidence to provide a better understanding of the mechanisms producing the abundance anomalies of these stars, and to establish the relationship between the two classes.

  4. 13. 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).

  5. 14. Use of localised techniques to elucidate the influence of process variables on the corrosion of stainless steels

    Författare :Nuria Fuertes; Rachel Pettersson; Inger Odnevall; Stuart Lyon; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stainless steel; corrosion; passive film; thermal oxides; Volta potential; pickling; deformation; cold rolling; AM; SKPFM; SVET; Kemi; Chemistry;

    Sammanfattning : Several factors during steel manufacture and fabrication can alter the passivity and corrosion behaviour of stainless steels. These include alloying, deformation, welding and heat treatments. LÄS MER

  7. 15. Some aspects on designing for metal Powder Bed Fusion

    Författare :Sebastian Hällgren; Lars Pejryd; Jens Ekengren; Robert Pederson; Örebro universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; AM; DfAM; lattice; Powder Bed Fusion; Topology optimization; Selective Laser Melting; Electron Beam Melting; Design for manufacturability;

    Sammanfattning : Additive Manufacturing (AM) using the Powder Bed Fusion (PBF) is a relatively new manufacturing method that is capable of creating shapes that was previously practically impossible to manufacture. Many think it will revolutionize how manufacturing will be done in the future. LÄS MER
