Crystal plasticitySuperalloyPhase-fieldCo-base superalloys with γ′-Co3(Al,W) precipitates show attractive properties in high temperature, while the creep concomitant with rafting of γ′ precipitates is a critical problem for this newly developed alloy. Creep properties and rafting morphology in Co...

Phase-field crystal modelling with MPI Overview The phase-field crystal (PFC) models liquid-solid phase transformations of crystals and can describe elasticity, plasticity and topological defects. The program is a finite-difference based implementation of the PFC model. It also enables to perform ...
A recently developed phase-field crystal (PFC) model incorporates elasticity and plasticity in the microstructural evolution of materials naturally by representing the density field for the crystalline state by periodic functions and by using a constant density for liquid state. PFC is of great interest...
Major segregating elements are identified, and the solidification patterns are modeled using the phase-field method. The subsequent martensitic transformation is simulated with crystal plasticity model. Finally the mechanical responses of various solidification microstructures are compared, using a ...
Phase-field method (PFM) has become a mainstream computational method for predicting the evolution of nano and mesoscopic microstructures and properties during materials processes. The paper briefly reviews latest progresses in applying PFM to understanding the thermodynamic driving forces and mechanisms unde...

Creep stress and grainsize exponents obtained for nanopolycrystalline systems, $m ...
This paper is devoted to the analytical and numerical study of stationary solutions of the one-dimensional Phase Field Crystal Equation. This new model recently introduced by K. Elder and M. Grant describes phase transformations at the atomic level on large time scales. By using bifurcation methods...
