What is ISO 23146 - Fracture toughness of monolithic ceramics about?
ISO 23146 is an international standard on fine ceramics which covers test methods for fracture toughness of monolithic ceramics. ISO 23146 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 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.
Who is ISO 23146 - Fracture toughness of monolithic ceramics for?
ISO 23146 on fracture toughness of monolithic ceramics is useful for:
- Fine ceramics manufacturers
- Mechanical engineers
Why should you use ISO 23146 - Fracture toughness of monolithic ceramics?
Monolithic ceramics are typified by their special features, such as reliability, durability and resistance to high temperatures, which makes them indispensable in some of the more demanding applications. These ceramics can be fabricated without a reinforcement material and have a polycrystalline microstructure.
With ISO 23146 specifying 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. This can help you in increasing safety in your organization.
