| Abstract |
In this paper, we investigated numerically gravity induced skeletal settling during liquid
phase sintering. The microstructural evolution will be simulated by simultaneous computation of
displacement of the center of mass and mass transport due to dissolution and precipitation at the
interfaces between solid-phase and liquid matrix. Common to this study based on domain
methodology for definition of regular multi-domain model will be the need to relate some diffusional
phenomena to essential geometric and topological attributes of the W-Ni porous microstructure
influenced by skeletal settling combined with extrication of some solid-phase domains during liquid
phase sintering. |
