Abstract

The Holm’s theory of electric contacts is used to establish of quantitative relation between conductivity of porous discrete fibers materials with the size of interparticle contacts. A computer modeling of distribution of density of current and temperatures in a single particle depending on the spark plasma sintering’s parameters was carried out.
