Moya, Influence of ceramic–metal interface adhesion on crack growth resistance of ZrO2–Nb ceramic matrix composites, Acta Materialia, Volume 56, Issue 14, 2008, Pages 3358-3366, ISSN 1359-6454, https://doi.org/10.1016/j.actamat.2008.03.021.1359-645410.1016/j.actamat.2008.03.021https://hdl.handle.net/20.500.14352/93245Yttria-stabilized zirconia strengthened with lamellar flaky-shape Nb metal particles was obtained by hot-pressing at 1500 °C for 1 h. The ZrO2–Nb interface has been studied by atomistic, first-principles calculations and by high-resolution transmission electron microscopy. The influence of the ceramic–metal interface on the crack growth resistance has been investigated. Crack growth is shown to occur with a rising resistance, governed by intact metal ligaments in the crack wake. Crack extension occurs by a combination of plastic deformation on the metal particles and interface debonding. The connection between the interface adhesion and this microstructural toughening mechanism has been evaluated.engjournal article1873-2453https://doi.org/10.1016/j.actamat.2008.03.021open access53ToughnessCermetsInterface structureHRTEMAb-initio electron theoryFísica (Física)22 Física
