A challenging task of spark plasma sintering (SPS) technology is the production of complex shape components. This limitation of SPS is mainly related to the difficulty to obtain homogenous microstructures and uniformly distributed density in the final components. An original solution for these issues can be found in the application of the mobile evolving interface approach. However, this method introduces shape distortions in the final object due to the presence of different powders and of nonuniform relative density distribution in the initial pre-SPS powder volume.
Therefore, a simulation tool that allows predicting the evolution of the controllable interface during SPS is required. A combined experimental and numerical study is conducted to investigate possible solutions of this problem. Two different methodologies to optimize the initial geometry of the controllable interface are developed. The first is based on the Dohelert experimental design and the second is based on the distortion inversion method.
