  4. 3. Microstructure and Properties of Additively Manufactured Tool Steels for Hot Stamping

    Författare :Miwen Yuan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tool Steels; Wear; Hot stamping; Additive Manufacturing; Softening Resistance;

    Sammanfattning : Hot work tool steels are commonly used to produce dies for hot stamping, where the steels are exposed to cyclic thermal and mechanical loads. There is a constant demand to improve the lifetime of the dies. Additive manufacturing (AM) provides new solutions for tool design. LÄS MER

  5. 4. The Influence of Steel Sheet Surface-Topography on Friction in Stamping

    Författare :Anders Wihlborg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Micro Plasto HydroDynamic Lubrication MPHDL ; EBT; ECD; EDT; WC index; SBT; surface topography; Micro Plasto HydroStatic Lubrication MPHSL ; tribology; steel sheets; Surface Indentation Test; bending under tension;

    Sammanfattning : Steel sheet is the prevalent material for car body panels. In the manufacturing of steel sheets a certain surface roughness is achieved from the ground or textured rolls used in the three final reduction steps. When manufacturing car body panels the sheets first are formed and then painted. LÄS MER

  7. 5. Hydro-mechanical forming of aluminium tubes : on constitutive modelling and process design

    Författare :Mikael Jansson; Larsgunnar Nilsson; Odd Sture Hopperstad; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydroforming; Aluminium Extrusions; Anisotropic material; Solid mechanics; Fastkroppsmekanik;

    Sammanfattning : Tube hydroforming is a forming method which has several advantages. By using pressure in combination with material feeding it is possible to manufacture products with high structural integration and tight dimensional tolerances. The forming method is especially suited for aluminium alloys which have a relatively low ductility. LÄS MER
