Abstract

Bioinspired “brick‐and‐mortar” alumina ceramics containing a nickel compliant phase are synthesized by coextrusion of alumina and nickel oxide. Results show that these structures are coarser yet exhibit exceptional resistance‐curve behavior with a fracture toughness three or more times higher than that of alumina, consistent with significant extrinsic toughening, from crack bridging and “brick” pull‐out, in the image of natural nacre. [Figure not available: see fulltext.]
