Abstract: A method of producing a component of a composite of diamond and a binder, wherein a Hot Isostatic gas Pressure process (HIP) is used, includes the step of enclosing a de-bound green body having compacted diamond particles in an infiltrant. The method includes the further steps of enclosing the de-bound green body and the infiltrant in a Zr-capsule that has Zirconium as a main constituent and sealing the Zr-capsule, and applying a predetermined pressure-temperature cycle on the unit formed by the de-bound green body, infiltrant and capsule in which the infiltrant infiltrates the de-bound green body and the de-bound green body is further densified in the sense that the volume thereof is decreased.

Abstract: The present invention relates to a method of making a cemented carbide comprising mixing in a slurry a first powder fraction and a second powder fraction, subjecting the slurry to milling, drying, pressing and sintering. The first powder fraction is made from cemented carbide scrap recycled using the Zn recovery process, comprising the elements W, C, Co, and at least one or more of Ta, Ti, Nb, Cr, Zr, Hf and Mo, and the second powder fraction comprising virgin raw materials of WC and possibly carbides and/or carbonitrides of one or more of Cr, Zr, W, Ta, Ti, Hf and Nb. The first powder fraction is subjected to a pre-milling step, prior to the step of forming the slurry, to obtain an average grain size of between 0.2 to 1.5 μm.
