Simulation Results

The densification of Ge-Si within spark plasma sintering has been simulated. The simulation was based on finite elements method and implemented in Comsol Multiphysics. The model of mechanical processes was based on the simulation results published earlier for metal and ceramic powder materials. The model included plastic and elastic deformation description, impact of porosity on electrical, thermal and mechanical properties. The pressure field in the sample has been calculated. The change of sample diameter due to the expansion and compression has been obtained for the soaking period.

Simulation Results

A new mathematical simulation technique for physico-mechanical properties of multicomponent powder materials is proposed in this paper. The main advantage of the technique is that finite elements representing different components are placed into a common mesh and may exchange their properties. The input data are properties of components and specified value of porosity. The output data are properties of material after sintering. The technique allows us to investigate the influence of each component of a material on the properties and distribution of properties inside the sample. The comparative analysis of materials with different compositions is based on simulation results that are well concordant with the results of the laboratory experiments.
