A program for analyzing density distribution in powder compact during pulse current sintering process has been developed. Temperature distribution during the sintering process is analyzed by the heat conduction finite element method, where the heat generation per unit volume induced by the electric current is considered. The densification is evaluated based on the temperature distribution. The effect of plastic flow, diffusion and creep phenomenon are taken into account in the densification analysis. Calculated temperature and densification histories are compared with the test results of the pulse current sintering and hot press sintering. The calculated results are in good agreement with the experimental ones. The validity of the algorithm was demonstrated.
