Combined effects of WC and SiC on densification and thermo-mechanical stability of ZrB2 ceramics

ZrB2-based mixtures containing WC and SiC in various amounts were hot-pressed at 1930°C, achieving final relative densities above 94%. The diboride matrix of the sintered ceramics was constituted by (Zr,W)B2 solid solution shells grown onto original ZrB2 grains. WC phase reacted during sintering lea...
