Numerical Simulation of the Temperature Field in Sintering of TiB_2-BN by SPS

摘要

The temperature field during the whole process of SPS sintering TiB_2-BN sample was numerically simulated based on the simplification of the temperature rising process. The result shows that the higliest temperature is found in the punch and the heat flows from punch to sample and die in SPS sintering system. In the radial direction, the center temperature of the sample is much higher than the circumference temperature of the sample. In the axial direction, the center temperature of the sample is lower than the border temperature of the sample. The temperature difference in the sample is growing bigger in the sintering process and reaches the maximum at the end of the heating-up process.
