    Abstract

    Finite element simulations have been conducted to investigate the heat distribution between the particles from contact resistance and current density during the Micro-forming Fields Activated Sintering Technology (Micro-FAST). Results of effect for the arrangement modes of powder particles (Series connection and parallel connection) showed that the electro-heat focusing could be attributed to the remarkable difference of contact resistance between the particles.
