Fine ceramics (advanced ceramics, advanced technical ceramics) - Test methods for fracture toughness of monolithic ceramics - Single-edge V-notch beam (SEVNB) method (ISO 23146:2012)

ISO 23146:2012 specifies a method for the determination of the fracture toughness of advanced technical ceramics. The procedure makes use of single-edge V-notched bars, which are loaded in four-point bending until failure. It is applicable to monolithic ceramics with a grain size or major microstructural feature size larger than about 1 µm.
The use of ISO 23146:2012 for yttria tetragonal zirconia polycrystal material (Y-TZP) is not recommended. The method might also be unsuitable for some other very tough or soft ceramics in which a sharp crack does not form at the root of the V-notch.

Hochleistungskeramik - Prüfverfahren zur Bestimmung der Bruchzähigkeit monolithischer Keramik - Verfahren für Biegeproben mit V-Kerb (SEVNB-Verfahren) (ISO 23146:2012)

Diese Internationale Norm legt ein Verfahren zur Bestimmung der Bruchzähigkeit von Hochleistungs-keramik fest. Bei diesem Verfahren werden einseitig gekerbte Biegeproben mit V-Kerb verwendet, die durch eine 4-Punkt-Biegung bis zum Bruch beansprucht werden. Das Verfahren gilt für monolithische Keramik mit einer Korngröße oder einer Größe eines anderen typischen Merkmals der Mikrostruktur von mindestens etwa 1 µm.
Die Anwendung dieser Internationalen Norm für Yttrium-stabilisiertes polykristallines tetragonales Zirko¬niumdioxid (Y-TZP) wird nicht empfohlen. Das Verfahren könnte auch für andere hochzähe oder weiche Keramikwerkstoffe ungeeignet sein, bei denen sich kein scharfer Riss am Grund des V-Kerbs bildet.

Céramiques techniques - Méthodes d'essai pour la détermination de la ténacité à la rupture des céramiques monolithiques - Méthode sur éprouvette à entaille en V sur une seule face (Méthode SEVNB) (ISO 23146:2012)

L'ISO 23146:2012 spécifie une méthode d'essai pour la détermination de la ténacité à la rupture des céramiques techniques. La méthode utilise des éprouvettes à entaille en V sur une seule face, qui sont chargées en flexion quatre points jusqu'à la rupture. Elle est applicable aux céramiques monolithiques avec une taille de grains ou une taille des principales caractéristiques microstructurales supérieure à environ 1 µm.
Il n'est pas recommandé d'utiliser l'ISO 23146:2012 pour le matériau polycristallin de zircone tétragonale d'yttria (Y-TZP). La méthode peut aussi ne pas convenir à d'autres céramiques très tenaces ou molles dans lesquelles une fissure tranchante ne se forme pas à la racine de l'entaille en V.

Fina keramika (sodobna keramika, sodobna tehnična keramika) - Preskusne metode za ugotavljanje odpornosti monolitske keramike proti lomljenju - Metoda upogibnega preskusa z V-zarezo (metoda SEVNB) (ISO 23146:2012)

Ta mednarodni standard določa metodo za ugotavljanje odpornosti sodobne tehnične keramike proti lomljenju. Postopek uporablja palice z enim robom in V-zarezo, ki se naložijo za štiritočkovno upogibanje, dokler se ne zlomijo. Uporablja se za monolitno keramiko z velikostjo zrn ali velikostjo glavne mikrostrukturne enote nad približno 1 µm. Uporaba tega mednarodnega standarda za material iz itrijevega tetragonalnega cirkonijevega polikristala (Y-TZP) ni priporočljiva. Metoda morda ni primerna tudi za nekatere druge vrste zelo trde ali zelo mehke keramike, pri kateri v korenu V-zareze ne nastane ostra razpoka.
