Numerical Simulation about Influence of Axial Alternating Magnetic Field on Temperature Field in EFAST

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.
