Resumo

The formation of the microstructure of ZrB2–B4C ceramic composites produced by SHS pressing has been studied. It has been shown that the exothermic interaction in a mixture of Zr, B, and C powders gives an equilibrium SHS product containing ZrB2 as a dispersed phase and B4C as a ceramic binder. The effect of the ceramic binder (B4C) content on the formation of the microstructure of SHS composites has been investigated.
