Abstract

We present a new, two dimensional phase field model of grain boundary statics and dynamics. We begin with a brief description and physical motivation of the crystalline phase field model. The description if followed by characterization and analysis of some noteworthy microstructural implications: the grain boundary energy as a function of misorientation, the dihedral angle, the wetting condition for a phase boundary and stabilized widths of intercalating phases at grain boundaries, and the potential for grain rotation as a mode of microstructural evolution. Simulations that demonstrate these implications are presented with a description of the numerical methods that were used to obtain them.
