Abstract:
In order to model the impingement of solidifying
crystals, we must have a suitable model of the
behavior of materials of differing crystallographic
orientations. Such boundaries are called grain
boundaries, and form one of the most basic
substructures in materials systems. In this talk we
will extend the previously developed phase field
model of solidification to include grain boundary
effects, and then explore physical phenomena such as
impingement, grain growth, grain boundary wetting,
polycrystalline alloy growth, dizzy dendrites and
spherulitic growth.
