Effect of graphite content on properties of B₄C‐W₂B₅ ceramic composites by in situ reaction of B‐Gr‐WC

Strip‐shaped W 2 B 5 reinforced B 4 C ceramic composites were prepared via in situ reaction of boron(B)‐graphite(Gr)‐ WC system by powder metallurgy (P/M). In order to study the effect of the graphite content on the properties of the as‐fabricated ceramic composites, the powder mixture of B‐Gr‐ WC with various amounts of Gr powder were blended and consolidated by spark plasma sintering ( SPS ). The sintering parameters were shown as following:...
