This paper proposed an improved thermal-electric-displacement FEM model for spark plasma sintering (SPS), which fully considered the variations of therma-electrical material parameters, contact resistances and contact boundaries due to the densification process. The simulation shows that such an alterable boundary condition builds a remarkable temperature gradient in the axial direction along the inner wall of the die, and the local change of the temperature at the contact interfaces can be described more exactly. The experiment and the simulation are in a great agreement. The developed SPS model can be used as an aiding tool to optimize the SPS process parameters of metal powders.
