A basic model for electric field activated sintering was presented by electromagnet theory, and the equations coupling electric field and temperature field were set up based on the theories of microscale heat transfer and electromagnetics. The thermoelectric phenomena in specimen, female die, punch during electric field activated sintering were simulated using the software FEMLAB. Numerical calculations were based on finite element analysis and the coupling of PDEs and electromagnetic modules. And the current density, resistance heating and temperature distributions in the specimen, female die, punch and their evolution during electric field sintering were obtained. The high heating rate and the obvious effect of current density on resistance heating, temperature distribution in specimen, female die, punch were found. The temperature of lower punch was measured using a thermocouple. The experimental results are in good agreement with those resulted from FEM, which indicates that FEM is valid analysis method to simulate temperature field in electric field activated sintering.

The method was proposed that adopts axial alternating magnetic field coupled with the pulse electric field in order to improve the temperature gradient during electric field activated sintering(EFAST).The results show that the maximum temperature difference in the products during EFAST coupled with magnetic field is reduced by 3/4 of that of only adopting pulse electric field.The reason is that the current induced by the magnetic field possesses skin effect,which generates more quantity of heat within the outer part and regulates the temperature distribution in EFAST.

提出了在电场活化烧结过程中施加轴向交变磁场与脉冲电场耦合改善烧结体径向温度场以减小其温度差的方法,并对不同大小磁场的作用进行了数值模拟。结果表明:施加轴向交变磁场可使横截面上的最大温度差减少3/4。其原因是交变磁场的感应电流具有集肤效应,可以使试样外部得到更多的热量。试验结果证明了模拟的准确性。
