  1. 1. Modelling phase separation in Fe-Cr alloys A continuum approach

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Thomas Barkar; John Ågren; Nele Moelans; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase separation; spinodal decomposition; nucleation; diffusion; thermodynamics; kinetics; steel; ferritic;

    Sammanfattning : The formation of Cr-rich and Fe-rich domains upon ageing of an initially homogeneous Fe-Cr alloy at elevated temperatures (300-600 ºC) is commonly referred to as phase separation. The behaviour originates from a miscibility gap in the Fe-Cr phase diagram. LÄS MER

  3. 3. Continuum Percolation in non-Euclidean Spaces

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Johan Tykesson; Göteborgs universitet.; Gothenburg University.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bernoulli percolation; continuum percolation; dependent percolation; double phase transition; hyperbolic space; Poisson Boolean model; geodesic percolation; continuum percolation; Poisson Boolean model; dependent percolation; hyperbolic space; double phase transition; geodesic percolation;

    Sammanfattning : In this thesis we first consider the Poisson Boolean model ofcontinuum percolation in $n$-dimensional hyperbolic space ${\mathbb H}^n$. Let $R$ be the radius of the balls in the model, and$\lambda$ the intensity of the underlying Poisson process. LÄS MER

  5. 5. On error controlled atomistic-to-continuum modeling with application to graphene monolayers

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Arash Memarnahavandi; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quasi-Continuum; stress-free; atomistic-to-continuum; homogenization; adaptivity;

    Sammanfattning : In order to consider virtual materials, i.e. materials that are not manufactured yet, it can be advantageous to model physical phenomena on a lower length scale than the macroscopic one. In such a case, homogenization (or coarse-graining) can be a useful tool. LÄS MER
