“…They also reported that the difference in thermal expansion of the sample and surrounding parts has a direct effect on resulted stresses. Yushin et al [28] investigated the temperature distribution and mechanical stresses in the sample and the mold numerically in alumina and tungsten carbide powders. In the samples made of aluminum oxide, they found a considerable diagonal temperature gradient.…”

The present work aims to investigate the geometrical parameters of the graphite die on energy consumption needed for sintering of a ZrB2 sample. The Maxwell and electrical charge conservation equations are solved to obtain the electrical potential and current of the system. The governing equations are discretized by the Galerkin method and solved using the finite element method. The electric current distribution is obtained at each geometry and the temperature contours are obtained. The results showed that the height of die has a direct effect on power consumption. This can be attributed to the increased electric resistance and consequent increased Joule heating. On the other hand, increasing the die height resulted in more uniform temperature distribution through the sintered sample.
