    摘要： A free standing PCD body comprises a PCD material formed of combination of intergrown diamond grains forming a diamond network and an interpenetrating metallic network, the PCD body not being attached to a second body or substrate formed of a different material. The diamond network is formed of diamond grains having a plurality of grain sizes, and comprises a grain size distribution having an average diamond grain size, wherein the largest component of the diamond grain size distribution is no greater than three times the average diamond grain size. The PCD material forming the free standing PCD body is homogeneous, such that the PCD body is spatially constant and invariant with respect to diamond network to metallic network volume ratio. The homogeneity is measured at a scale greater than ten times the average grain size and spans the dimension of the PCD body. The PCD material is also macroscopically residual stress free at said scale.

    摘要： A superhard structure comprises a body of polycrystalline superhard material comprising a first region and a second region, the second region being adjacent an exposed surface of the superhard structure, the second region comprising a diamond material or cubic boron nitride, the density of the second region being greater than 3.4×103 kilograms per cubic metre when the second region comprises diamond material. The material(s) forming the first and second regions have a difference in coefficient of thermal expansion, the first and second regions being arranged such that this difference induces compression in the second region adjacent the exposed surface. The fir further region has the highest coefficient of thermal expansion of the polycrystalline body and is separated from a peripheral free surface of the body of polycrystalline superhard material by the second region or one or more further regions formed of a material or materials of a lower coefficient of thermal expansion. The regions comprise a plurality of grains of polycrystalline superhard material. There is also disclosed a method of making such a material.
