Thermal shock resistance of polycrystalline cubic boron nitride [PDF]
Journal of the European Ceramic Society, 2012 Abstract The effect of thermal shock on the flexural strength has been investigated experimentally. It was found that the variation in flexural strength with quench temperature was influenced by the CBN grain size. Polycrystalline material containing small CBN grains showed a discontinuous drop in measured flexural strength above a material dependent
