di meccanismi di tenacizzazione. Fra i molti meccanismi riscontrati, in questo lavoro si è esaminato quello associato alla trasformazione di fase con espansione volumetrica caratteristico della zirconia parzialmente stabilizzata. Si è considerato il sistema composito particellato allumina/zirconia e se ne è ottenuta sperimentalmente la tenacità a frattura in funzione dalla percentuale di zirconia. La si è quindi analizzata in base ad un modello meccanico di frattura di una matrice con particelle soggette ad espansione evidenziando che il solo meccanismo di trasformazione di fase non è in grado di spiegare l’evidenza sperimentale. Individual toughening mechanisms affects remarkably the fracture resistance of ceramics. The role of stress-indu...
