Kinetic Monte-Carlo simulations of sintering

摘要

We simulate the sintering of particle aggregates due to surface diffusion. Asa method we use Kinetic Monte-Carlo simulations in which elasticity canexplicitly be taken into account. Therefore it is possible to investigate theshape relaxation of aggregates also under the influence of an externalpressure. Without elasticity we investigate the relaxation time and surfaceevolution of sintering aggregates and compare the simulations with theclassical Koch-Friedlander theory. Deviations from the theoretical predictionswill be discussed.
