  1. 1. Micromechanical study of PFZ in aluminum alloys

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Hossein Shariati; [2016]
    Keywords : precipitate-free zones; strain gradient plasticity; mikromekanik;

    Abstract : There are a number of experiments showing that the ductility of aluminum alloys decreases during age-hardening heat treatment. Observing the grains of age-hardened aluminum alloys at the micron scale, one can notice that there are precipitate-free zones (PFZs) along the grain boundaries. READ MORE

  3. 2. Micropumps for extreme pressures
