  1. 6. Numerical Methods for Simulating the Metal Shearing Process : A Novel Numerical Model for the Punching of Metals

    University essay from Luleå tekniska universitet/Material- och solidmekanik

    Author : Andreas Svanberg; [2019]
    Keywords : Punching; Blanking; Smoothed Particle Galerkin; SPG; LS-DYNA; FEM; Metal shearing; cutting; particle method; thesis; Stansning; klippning;

    Abstract : When dealing with the separation of materials, the metal shearing process such as punching, is widely used in theindustry due to its time efficient manner. There is however, a need to better understand the process in order toimprove quality of the final product. READ MORE

  3. 7. In-situ Reduction by Incorporating H2 Filled Hollow Glass Microspheres in PM HIP Capsules

    University essay from KTH/Materialvetenskap

    Author : Emil Strand; [2018]
    Keywords : Hot isostatic pressing; hollow glass microspheres; powder metallurgy; oxide reduction; surface oxides; hydrogen;

    Abstract : For many metal components the presence of hard, non-metallic inclusions such as oxides lowers the impact toughness by acting as fracture initiation points and easing crack propagation. In components produced by powder metallurgy hot isostatic pressing (PM HIP), oxides often form a continuous network of small, spherical inclusions after consolidation at the prior particle boundaries (PPB).

  4. 8. Self Lubricating Components

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Simon Tidén; Niklas Levin Bjärnlid; Tim Melin; Daniéla Quist; Filip Selenius Larsson; [2017]
    Keywords : self lubricating; solid lubricant; high speed steel; powder metallurgy; friction; wear; molybdenum disulfide; tungsten disulfide; hexagonal boron nitride; soft metals; copper;

    Abstract : The tribological and mechanical properties are of great importance for a material’s lifetime, since it is highly dependent on these two factors. The purpose of this report was to examine suitable solid lubricants for Erasteel, a company that manufactures hot isostatic pressed high speed steels, that will enhance the tribological properties of their steels without worsening the mechanical properties.

  6. 10. Investigation of the mechanical performance of metal-composite joints

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Marc Olavide Rubio; [2017]
    Keywords : carbon fiber epoxy; AlSi-coated boron steel; metal-composite joints; double-cantilever beam test; end-notched flexural test; tensile test;

    Abstract : Composite materials are gaining the attention of several industries due to the high stiffness-to-weight and strength-to-weight ratios they offer. Especially in the automotive industry, demands on reduction of CO2 emissions is the major driving force towards lighter vehicles. READ MORE
