FIELD: superhard materials produced in high-pressure and high-temperature apparatuses. SUBSTANCE: in a shape-forming insertion piece, vertical layers are successively placed, which constitute metal composition pressed in the form of object to be fabricated and made up of ternary intermetallic compounds CuAlTi, CuAlTi, CuAlTi, CuAlTi, CiAlTi; abrasive layer containing mixture of preliminarily Al-metallized powders of cubic boron nitride and diamond and hard alloy composition taken in specified proportion; and relaxation layer made after configuration of piece to be fabricated from the above hard alloy. Method may be applied in production of hard cutting tools. EFFECT: increased cutting ability of objects. |
