[ 1 ] - Finite element simulation of pyroplastic deformation, anisotropic shrinkage and heterogeneous densification for ceramic materials during liquid phase sintering process
Pyroplastic deformation is a distortion of the ceramic shape during the sintering process. It occurs because the flow of the vitreous phase at high temperature and the applied stress due to the weight of the product during sintering process. The aim of this paper deals with describing a numerical-experimental method to evaluate the pyroplastic deformation, to predict the anisotropic shrinkage a...
[ 2 ] - Evaluation of Heterogeneous Densification, Anisotropic Shrinkage and Rheological Behavior of Ceramic Materials during Liquid Phase Sintering by Numerical-Experimental Procedure
The effective shear and bulk viscosity, as well as dynamic viscosity, describe the rheological properties of the ceramic body during the liquid phase sintering process. The rheological parameters depend on the physical and thermo-mechanical characteristics of the material such as relative density, temperature, grain size, diffusion coefficient, and activation energy. Thermal behavior of the cer...
[ 3 ] - Affectability of ceramic nanoparticles of different compound from surface characteristics in AC electrophoretic deposition
Surface characteristic of particles is one of the main parameters controlling the properties of deposited layer in electrophoretic deposition. To modify the surface characteristic of particles, one of the methods is the addition of additives to the suspensions of powder-solvent. There are many reports dealing with the effect of surface characteristics of particles on uniformity and pattern of d...
