Microdesigning of Lightweight/High Strength Ceramic Materials

The New Generation of High Toughness Ceramics

“…Trends in ductile particle toughening with bridge length. Full implementation of the bridging mechanism requires further understanding of the ' strength' parameter, S. Available evidence 18,20 reveals that the avoidance of premature rupture of the metal/ceramic interface, leading to unacceptably low values of S, requires direct ceramic/metal bonding. When such intimate interfacial bonding has been achieved, plastic deformation extends across the metal around the crack 19 plane, causing the particle strength to be dictated by ductile rupture.…”
