  1. 1. Wear in sheet metal forming

    Författare :Anders Gåård; Pavel Krakhmalev; Jens Bergström; Åsa Kassman; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction; Sheet metal forming; Galling; Materials science; Teknisk materialvetenskap; Materialteknik; Materials Engineering;

    Sammanfattning : The general trend in the car body manufacturing industry is towards low-series production and reduction of press lubricants and car weight. The limited use of press lubricants, in combination with the introduction of high and ultra-high strength sheet materials, continuously increases the demands of the forming tools. LÄS MER

  3. 2. On Adhesion and Galling in Metal Forming

    Författare :Magnus Hanson; Sture Hogmark; Ulf Olofsson; Uppsala universitet; []
    Nyckelord :Engineering physics; adhesion; galling; dry sliding; stainless steel; vanadium nitride; metal forming; Teknisk fysik;

    Sammanfattning : Metal forming is widely used in the industry to produce cans, tubes, car chassis, rods, wires etc. Forming certain materials such as stainless steel, aluminium and titanium, is often difficult, and problems associated with transfer of work material to the tool material are frequent.

  7. 5. Nanoscale structure forming processes : Metal thin films grown far-from-equilibrium

    Författare :Viktor Elofsson; Kostas Sarakinos; Robert D. Boyd; Diederik Depla; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Thin film growth from the vapor phase has for a long time intrigued researchers endeavouring to unravel and understand atomistic surface processes that govern film formation. Their motivation has not been purely scientific, but also driven by numerous applications where this understanding is paramount to knowledge-based design of novel film materials with tailored properties.
