The relation between the distribution of dihedral angles and the wetting angle during liquid phase sintering

This study presents a Monte Carlo method to simulate the effect of the wetting angle on a dihedral angle distribution and on a degree of the grain boundary penetration of a liquid phase during liquid phase sintering. For the high probability for wetting, the number of the grain boundary penetration of a liquid phase increased while the wetting angle decreased and a few bonded grains maintained a stable grain boundary with high dihedral angles. This finding contradicts the classical prediction that smaller values of mean dihedral angles produce superior wettability. (c) 2005 Elsevier B.V. All rights reserved.
