摘要： The present invention relates to a sintered titanium based carbonitride alloy for milling and turning where the hard constituents are based on Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and/or W and 3-25 % binder phase based on Co and/or Ni. The alloy is characterized in that the bottom of crater caused by the crater wear consists of grooves with a mutual distance between their peaks of 40-100 µm, preferably 50-80 µm, and where the main part, preferably >75 % of the grooves have a height of >12 µm, preferably >15 µm.

摘要： According to the present invention there is now provided a method of making a sintered tianium-based carbonitride alloy. According to the method melt-metallurgical raw materials containing the metallic alloying elements for hard constituent forming as well as binder phase forming elements are melted and cast, using no intentional additions of the elements C, N, B and O, to a pre-alloy which in solidified condition essentially consists of brittle intermetallic phases with hard constituent forming and binder phase forming elements mixed in atomic scale. The pre-alloy is crushed and/or milled to powder with grain size

摘要： The present invention relates to a method of making a WC-Co-based cemented carbide with a fine WC-grain size. The cemented carbide is produced from well deagglomerated or easy to deagglomerate WC powder with round morphology, a Co powder also well deagglomerated or easy to deagglomerate and with a grain size equal to or smaller than the WC grain size and grain growth inhibitors. According to the invention the metal part of the grain growth inhibitors is added as part of the binder phase i.e. is included in the Co powder and alloyed therewith.
