Computer Simulation of Liquid Redistribution Induced by Rearrangement During Liquid Phase Sintering

In this paper liquid redistribution will be investigated taking into account either pure grain rearrangement or both grain rearrangement and coalescence of liquid bridges simultaneously. The grain rearrangement during liquid phase sintering will be generally accepted as driven by the capillary forces between solid grains embedded in liquid matrix. The coalescence of liquid bridges will be modeled as process in which two or more bridges join to form a larger one. Computer-based method will be applied for investigation weather liquid redistribution during LPS is governed by geometrical factors and/or nearest neighbor interaction due to capillary forces between adjacent grains. In order to avoid shrinkage by other processes than rearrangement, in this approach the system W-Cu will be chosen since tungsten is practically insoluble in liquid copper.
