  • Composite material, articles comprising same and method for making same
    Patent number: 10202308
    Abstract: Composite material comprising aluminum nitride (AlN) material, less than 80 weight percent cubic boron nitride (cBN) grains dispersed within the AlN material and less that 5 weight percent sinter promotion material, the composite material including no more than about 1.5 percent porosity.
    Type: Grant
    Filed: April 25, 2014
    Date of Patent: February 12, 2019
    Assignee: ELEMENT SIX LIMITED
    Inventors: Leif Sandström, Selim Dagdag, Lars-Ivar Nilsson, Karolina Hannersjö
  • PCBN MATERIAL, TOOL ELEMENTS COMPRISING SAME AND METHOD FOR USING SAME
    Publication number: 20160083301
    Abstract: PCBN material comprising at least 30 volume per cent cubic boron nitride (cBN) grains (10) bonded together by a matrix comprising aluminium nitride (20), and a plurality of regions (30) comprising boron and aluminium atoms, in which regions there are at least 15 times more boron atoms than aluminium atoms present. The regions comprise an aluminium boride phase of the inorganic chemical formula Al xBy, where x is at least 0.8 and at most 1.2, and y is at least 15, the ratio y:x being at least 15. The cubic boron nitride ceramic has been made by mixing cBN and Al grains and sintering at at least 1500 degrees Celcius and 4.5 GPa.

  • SUPER-HARD STRUCTURE, TOOL ELEMENT AND METHOD OF MAKING SAME
    Publication number: 20150218056
    Abstract: A method for making a treated super-hard structure, the method including providing a super-hard structure comprising super-hard material selected from polycrystalline cubic boron nitride (PCBN) material or thermally stable polycrystalline diamond (PCD) material; subjecting the super-hard structure to heat treatment at a treatment temperature of greater than 700 degrees centigrade at a treatment pressure at which the super-hard material is not thermodynamically stable, for a treatment period of at least about 5 minutes to produce the treated super-hard structure.
