  4. 17. On Adhesion and Galling in Metal Forming

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

    Abstract : 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.

    Abstract : Paper materials have a long history of use as a packaging material, although traditional paper-based packaging is limited in its shape, complexity, and design. In order to better understand the deformation and failure mechanisms during 3-D forming, two experimental studies of paper materials have been conducted. READ MORE

  7. 20. Wear mechanisms in sheet metal forming : Effects of tool microstructure, adhesion and temperature
