Models of normal grain growth can either start from a postulated kinetic law for individual grains and yield a distribution of grain sizes or they can start from a postulated distribution and the kinetic law may be derived. Both methods are studied and a whole family of distributions based on new ki
## Abstract A phase field model of grain growth in thin films on rigid substrates is presented, in which the motion of grain boundaries is driven by curvatures as well as anisotropy in surface, interface, and strain energies. The match between the proposed model and the corresponding sharp interfac
The growth competition of two grains, with orientations (1 1 0) and (1 0 0), during directional solidification of silicon is simulated by using a phase field model. The two-dimensional simulations show two distinct competition mechanisms, with either interfacial or kinetic dominance, depending on th
