标准范围
This International Standard specifies a method for the determination of the fracture toughness of advancedtechnical ceramics. The procedure makes use of single-edge V-notched bars, which are loaded in 4-pointbending until failure. It is applicable to monolithic ceramics with a grain size or major microstructural feature sizelarger than about 1 lJ.m.The use of this International Standard for yttria tetragonal zirconia polycrystal material (Y-TZP) is notrecommended. The method might also be unsuitable for some other very tough or soft ceramics in which asharp crack does not form at the root of the V-notch.
