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.

摘要： Abrasive compacts, in particular ultrahard polycrystalline abrasive compacts, are made under high pressure/high temperature conditions and are characterized in that they include a coarser grained fraction of ultrahard particles distributed non-percolatively throughout a finer grained fraction of ultrahard particles, which may be regarded as a finer grained ultrahard particle matrix, in such a way that the individual coarser grains are largely isolated from one another. It therefore performs as a matrix of highly wear resistant finer grained material interspersed with larger grains, offering a structure that has advantageous wear and impact performance over the behaviours of the two components individually or otherwise combined.
