Modeling of thermal processes during electroconsolidation
Keywords:
electroconsolidation, finite element simulation, thermal processes, Al2O3-SiC
Abstract
Practical application of mathematical modeling technologies of heat transfer processes in the main units of the installation for electroconsolidation of powder materials using FAST/SPS technology is considered. A mathematical model of the existing hot pressing unit with direct current transmission is created.
The results on the heat distribution in the installation parts and in the compaction zone are obtained. Comparison of simulation results with experimental data is given. The significance of the data obtained by using similar techniques, both from the fundamental point of view and from the practical one, is shown.
