Dataset contains results of phase field simulations of coarsening via surface diffusion conducted using the model proposed by Rätz, Ribalta, and Voigt (2006) with isotropic interfacial energy. Compositions with equilibrium volume fractions of 32%, 36%, and 50% were simulated. The types of data included are raw simulation output, interfacial shape distributions (ISDs), radially averaged autocorrelations of the phase and the interfacial mean curvature, and spreadsheets describing the evolution of characteristic morphological and topological quantities during each simulation. For the 32% case, additional data is included that characterizes particles that detach from and reattach to the main structure. For the 36% and 50% cases, the radially-averaged structure factor of the phase field is provided.
