摘要：
To determine the temperature distribution both on contact boundaries and directly in each of two materials during their simultaneous spark plasma sintering, the solution of the thermal problem has been used and a computational program has been developed. The heating of an alumina sample with tungsten, nickel, and graphite baffles is considered. It is found that electrical heating of materials with high electrical conductivity occurs with small temperature gradients in both the axial and radial directions, which has made it possible to develop an additive method for obtaining large-size blanks of such materials.
