摘要： Provided are niobium carbide-based cemented carbides and methods of manufacturing the same. The niobium carbide-based cemented carbides may be free of WC. Additionally, or alternatively, the niobium carbide-based cemented carbides may have a hard phase in which NbC in present in an amount greater than any other element of the hard phase. The niobium carbide-based cemented carbide may also have a binder phase devoid of Co.

摘要： A cBN material and a method of making a cBN material, the method including the steps of providing a powder mixture comprising cBN grains, aluminum and a Ti(CxNyOz)a powder, subjecting the powder mixture to a milling to form a powder blend, subjecting the powder blend to a forming operation to form a green body, subjecting the green body to a pre-sintering step, at a temperature between 650 to 950° C., to form a pre-sintered body, and subjecting the pre-sintered body to a HPHT operation to form the cBN material. For the Ti(CxNyOz)a powder, 0.05≤z≤0.4. In addition, a cBN material includes cBN grains, an Al2O3 phase, a binder phase of TiC, TiN and/or TiCN, W and Co, whereby a quotient Q is
