The effect of mechanical activation of the reaction mixture on the formation of the microstructure of ZrB2‒CrB composites obtained by electrothermal explosion under pressure

Abstract
Composites ZrB2‒CrB with a ceramic bond content of 80 wt. % and relative density 0,85‒0,90 were obtained by the method of electrothermal explosion (ETЕ) under pressure. It is shown that mechanical activation (MA) of the initial powder mixture reduces its heterogeneity and increases its reactivity. A fine ceramic composite with a homogeneous microstructure was obtained containing needle-like ZrB2 grains. Ill. 5. Ref. 13.
