  2. 1. Efficient crystal plasticity simulations of microstructure evolution

    Author : Ylva Mellbin; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : One of the common tools for studying the deformation behavior of the microstructure in polycrystalline materials is crystal plasticity models. These are used to describe texture evolution and hardening due to crystallographic slip. READ MORE

  4. 2. Multiscale modeling of dynamic recrystallization

    Author : Ylva Mellbin; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic recrystallization; Crystal plasticity; Texture; Grain size strengthening; Vertex model; Nucleation; Particle pinning; Large deformations; Multiscale modeling; GPGPU;

    Abstract : During thermomechanical processing of metals, changes occur in the microstructure of the material which affect its macroscopic properties. By understanding these transformations in the microstructure, it becomes possible to design the processes in a way which yields the desired properties in the finished product. READ MORE

  5. 3. Phase-field modeling of stress-induced precipitation and kinetics in engineering metals

    Author : Claudio F. Nigro; Christina Bjerkén; Ylva Mellbin; Pär A T Olsson; Reinhart Pippan; Malmö universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-field theory; finite element method; corrosion; finite volume method; phase transformation; hydride; hydrogen embrittlement; linear elastic fracture mechanics;

    Abstract : The formation of brittle compounds in metals operating in corrosive environments can be a tremendous source of embrittlement for industrial structures and such phenomenon is commonly enhanced in presence of stresses. To study this type of microstructural change modeling is preferred to experiment to reduce costs and prevent undesirable environmental impacts. READ MORE
