Abstract

Time-dependent change of electrical resistance for 56 vol. % Al2O3+36 vol. % TiC + 8 vol. % ZrO2 sample, obtained by means of electrical consolidation has been investigated in the article. The mechanism of carbon concentration change while compacting has been investigated and it was determined that under the condition that the content is 36 vol. % TiC, that slightly exceeds percolation threshold, it is possible to obtain a dense sample having grain shape different from spherical. That allows us to reach coordination number 4 to provide the percolation process possibility.
