Effect of high-energy mechanical activation of dispersed systems on the structure of composite materials ZrB2–SiC
The effect of high-energy mechanical processing of ZrB2 and ZrB2-SiC dispersed systems was studied. It was shown that mechanical processing of powders at 30g acceleration in a planetary mill leads to activation, which is accompanied by the appearance of new interfaces in particles (a decrease in the coherent scattering region size) and microdeformations of the ZrB2 crystal lattice. Mechanical processing of the powders was accompanied by an increase in the specific surface area, resulting in the formation of dense aggregates. Increasing the duration of mechanical processing contributed to an increase in the density of ZrB2 ceramics and ZrB2-SiC ceramic composites. The ZrB2-SiC ceramic composite material possessed the highest relative density.
