Fig. 1: Schematic of bioinspired design and fabrication of high-entropy carbide (HEC)/Cr7C3 all-ceramics.
From: Tough and strong bioinspired high-entropy all-ceramics with a contiguous network structure
a Brick-and-mortar structure of nacre. b Contiguous network structure of spongy bone. c Tough and strong all-ceramics with a contiguous network distribution of the Cr7C3 plastic phase within the predominant HEC hard phase. Fabrication process of the tough and strong all-ceramics: d Uniformly mixing the different raw powders (represented as colored spheres) and then heating the mixture to high temperature within seconds using an ultrafast high-temperature synthesis (UHTS) technique, e densifying the obtained HEC/Cr7C3 core-shell intermediate powders using a spark plasma sintering (SPS) technique, and f resulting in the final HEC/Cr7C3 all-ceramics.
