Recent results using a phase field model of polycrystalline alloy
dynamics are presented, using two numerical techniques: adaptive
grids and parallel grids. The growth of alloy dendrites, and their
subsequent impingement to form grain boundaries is demonstrated
within the model, and topics for future research are discussed.
