Coarsening of Complex Microstructures via Surface Diffusion
|
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.

Coarsening in 3D at 50% Volume Fraction with Dissimilar Mobilities
|
Dataset contains results of two phase field simulations of coarsening where the Cahn-Hilliard mobility differs by a factor of 100 between the two phases. Interfacial energy is isotropic, and the nominal volume fractions of the phases are 50%-50%. The two simulations represent different initial conditions for coarsening. The simulation "Random noise initial condition" was initialized from random noise and simulated with dissimilar mobilities for its entire duration. In the simulation "Phase-separated initial condition", phase separation and early coarsening (within the first 2e5 iterations) were simulated with constant mobility, and subsequent coarsening was simulated with dissimilar mobilities. These two conditions resulted in different in initial morphologies and transient evolution. The types of data included are raw simulation output, interfacial shape distributions (ISDs), and a spreadsheet of characteristic quantities for the structure. Details regarding the simulation and characterization methods can be found in our paper located at https://doi.org/10.1016/j.commatsci.2019.109418.

Coarsening of Particles with Bimodal Size Distribution, 2-D Phase Field Dataset
|
This dataset contains the results of a numerical experiment to test the relationship between morphological self-similarity and dynamic scaling during coarsening using an initial structure with distinct populations of large and small particles. The small particles coarsened self-similarly, so agreement with the t^(1/3) dynamic scaling law was observed despite a lack of self-similarity of the overall structure due to the slow evolution of the large particles. The dataset contains raw simulation output and characterization results. Additional details regarding the generation of this dataset are contained in our paper located at https://doi.org/10.1038/s41598-018-36354-8. The authors acknowledge support from the U.S. Department of Energy, Basic Energy Science, DE-FG02-99ER45782.

Coarsening in 3D at Volume Fractions 30%-36%
|
This dataset contains results of phase field simulations of coarsening with constant mobility, isotropic interfacial energy, and compositions with nominal volume fractions of 30%, 32%, 34%, and 36%. The types of data included for all four simulations are raw simulation output, interfacial shape distributions (ISDs), and a spreadsheet containing the time evolution of characteristic quantities of the structure. Additional types of data provided for selected structures include the radially-averaged autocorrelations of the segmented phases and the interfacial mean curvature (32% and 36%) and the radially-averaged structure factor of the phase field (36%). In files that contain data from a single simulation time, simulation time is typically indicated in the filename by the iteration number (i.e., the simulation time divided by the time step size, which is 0.05).
