Modeling growth of a macropore on the interphase boundary

S3D Evolution models sintering of powder bodes with interphase boundaries. Computational experiments allow determining the way the quality of sintering two-phase disperse systems depends on geometry of phase separation surface.

Fig. 1. Model structure evolution during the modeling of two-phase disperse system sintering. Sintering is modeled with the diffusion-viscous flow mechanism. Interphase boundary geometry causes genesis of the: (a) through macropore, (á) open macropore, (c) homogenous sintering. t = 1,0[hrs] corresponds with 1 hour duration of practical sintering Fig. 2. Temporal dependencies of relative density P of the two-phase model disperse systems with different interphase boundary morphology, for each for all other sintering conditions being equal, the following objects generate: (1) through macropore, (2) open macropore, (3) no macropore
