Kinetic Monte Carlo Simulation of 3D Sintering

Christina Garcia-Cardona
Claremont Graduate University

We present a three-dimensional parallel implementation of a Potts kinetic Monte Carlo model (kMC) that simulates the microstructure evolution during sintering. The model accounts for the main mechanisms operating during sintering, including curvature driven grain growth, pore migration by surface diffusion, and vacancy formation and annihilation leading to densification. The parallel implementation is based on the SPPARKS (Stochastic Parallel PARticle Kinetic Simulator) code from SNL and enables the analysis of compacts composed of hundreds of particles at different densification levels. The effectivity of the kMC model is illustrated through several examples with different particle compacts. The talk is based on joint work with Veena Tikare, Burton R. Patterson and Eugene Olevsky.
