Interplay between Surface and Grain Boundary in Sintering

Abstract:

Article Preview

Three-dimensional numerical simulation of sintering was performed to illustrate the interplay between surface and grain boundary in particle scale. The shrinkage during sintering can be described as a motion of the center of mass by the force acting between particles, that is, the sintering force. When a particle interacts with several neighbor particles, the sintering force on the particle is a vector sum of forces acting through grain boundaries with neighbors. A particle changes its own shape through interaction with neighbor particles, then, the coordination number affects particle motion.
