Abstract

The finite element method is employed to simulate the microstructural evolution through grain coarsening within capillary liquid bridge. Liquid and solid phase domains will be represented with curved interfaces defined by the discrete set of points. Numerical method for simulation of grain coarsening will be based on the interfacial concentration as given by the Gibbs-Thomson equation and on modeling of intergrain diffusional interactions. It will be shown that the strong intergrain diffusional interactions can induce large shape distortion of multi grain model. Simulation of the grain coarsening for W-Ni alloy will be demonstrated as a first step.
