Paper Title:
Numerical Analysis on Temperature Field of Axial Alternating Magnetic Field-Assisted Electric Field-Activated Sintering
  Abstract

The numerical simulation and experimental measurement of temperature distribution in electrical field activated sintering of titanium powders were carried out. The simulated and experimental results were in good agreement. It was shown that the sintering temperature gradually decreased from the center of sample to the outer. To improve the performance of sintered material, the sintering temperature gradient had to minimize. A method, electric field-activated sintering coupled with axial alternating magnetic field, was proposed to homogenize sintering temperature field. The simulation of sintering temperature field was also conducted under different magnetic field intensity. It was proved that the maximum radial sintering temperature difference in sample was reduced by about three fourths, owing to the skin effect of induced current caused by alternating magnetic field.
