Kinetic Monte-Carlo simulations of sintering — •Frank Westerhoff, Ruslan Zinetullin, and Dietrich E. Wolf — Computational Physics, Universität Duisburg-Essen

We simulate the sintering of particle aggregates by means of surface diffusion. As a method we use Kinetic Monte-Carlo simulations in which elasticity can explicitly be taken into account. Therefore it is possible to investigate the shape relaxation of aggregates also under the influence of an outer pressure. Without elasticity we investigate the relaxation time and surface evolution of sintering aggregates and compare the simulations with the classical Koch-Friedlander theory. Differences to the theoretical predictions will be discussed.
