Influence of initial parameters of reacting systems on the porosity structure of self-propagating high-temperature synthesis products

Abstract

The effects of the particle size of powder components, the relative density of the sample, and the degree of dilution of the mixture by thermally inert materials on the pore structure of self-propagating high-temperature synthesis products obtained in the combustion process involving melt were experimentally studied using the (Ti + 26% Si)-Al2O3 system as an example. Special techniques of quantitative metallographic analysis allowing for the analysis of materials with complex pore space structure were used.
