The second region is adjacent an exposed surface of the superhard structure and comprises a diamond material or cubic boron nitride with a density greater than 3.4x103 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 first/a further region has the highest coefficient of thermal expansion of the polycrystalline body and is separated in part from a peripheral free surface of the body by the second region or one or more further regions formed of a material(s) of a lower coefficient of thermal expansion. The regions comprise a plurality of grains of polycrystalline superhard material. The second region is peripherally discontinuous with a gap therein through which a portion of the region formed of the material of highest coefficient of thermal expansion extends to the free surface of the superhard structure. There is also disclosed a method for making such a structure.

摘要： An ultrahard composite material comprises ultrahard particles dispersed in a phase transformable matrix material. The phase transformable matrix material is a single material including all possible crystallographic phases thereof, that comprises at least one component that is metastable at or near ambient temperature and the metastable component is capable of undergoing Martensitic phase transformation when the composite material is placed under stress, for example stress with a significant shear component. The stability of the matrix material at ambient temperature, and its ability to undergo phase transformation, is enhanced or optimised by ensuring that the matrix material comprises predominantly the crystallographic phase that is the metastable phase and/or by providing the matrix material in a nano grain size range that ensures it is metastable at or near ambient temperature. The metastable phase present will transform when stresses are applied during applications such as the machining of hard materials and the like.

摘要： The present invention concerns a method of producing an ultrahard abrasive composite material having a desirable overall thermal expansion coefficient mismatch, between the ultrahard particles and their matrix materials. The method includes the steps of providing a volume fraction of ultrahard particles having a pre-determined thermal expansion coefficient; determining the volume fraction and thermal expansion coefficient of a matrix material that would be required to produce an ultrahard composite material having a desired overall thermal expansion coefficient mismatch; contacting the ultrahard particles and the matrix material to form a reaction volume; and consolidating and sintering the reaction volume at a pressure and a temperature at which the ultrahard particles are crystallographically or thermodynamically stable. Ultrahard composites where the ultrahard particles are cubic boron nitride and/or diamond are provided, with matrix materials chosen to produce thermal expansion mismatches within specific value ranges, and associated, controlled residual stresses. Ultrahard composite matrices involving combinations of nitride matrices such as titanium nitride/tantalum nitride, and titanium nitride/ chromium nitride are exemplified.
