Effect of ZrB2 content on the densification

HEBM induced homogeneous mixing and particles size reduction of the starting powders, which promoted low temperature sintering. In our previous study, two phase ZrC-SiC ceramics containing 0 to 30 vol% SiC were produced at 1900 °C by HEBM and RHP of ZrH 2, carbon black, and SiC powder mixtures . The addition of SiC as a …

On the crystallite size refinement of ZrB2

The effect of SiC addition (5, 17.5, and 30 vol.%) on the high-energy ball-milling (HEBM) behaviour of ZrB 2 is investigated. It was found that the presence of SiC during HEBM did not alter ZrB 2 refinement mechanism of repeated brittle fracture followed by cold-welding, thereby leading to the formation of agglomerates consisting of primary …
