  • Publication number: 20130287625
    Abstract: Provided is a high hardness ultra-fine cemented carbide with a Ni binder phase for a wear resistant tool. An ultra-fine cemented carbide having high specularity and/or high strength, high hardness, and high wear resistance is obtained by using an ultra-fine raw powder of WC, controlling the amount of Ni, and the contents of V and Cr, so that a third phase containing V and Cr precipitates in a microstructure of the cemented carbide in a finely dispersed state, and at the same time, the size of Ni pool is controlled to a value equal to or less than the average grain size of WC. By using this cemented carbide, the range of application to an aspherical glass lens mold, an ultrahigh pressure generation container for neutron diffraction experiment, a non-ferromagnetic corrosion resistant and wear resistant tool, and the like is expanded.
