Coalescence of precipitates is a common kinetic phenomenon. The phase-field method can simulate coalescence of precipitates without any ad hoc assumptions. However, independent of long range effects (e.g. lattice misfit) the method predicts a high coalescence rate when applied to systems with a high volume fraction of precipitates. We show that this is a result of ignoring the ...
