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： Provided is a cemented carbide suitable for use as a material in the manufacture of a punch for metal forming and in particular for the manufacture of metal beverage cans. The cemented carbide may include a hard phase that includes WC, a binder phase and a gamma phase. The gamma phase may include metal carbides in combination with metal nitrides or metal carbonitrides. A quotient of the average grain size of WC/the average grain size of the gamma phase may be in a range of from 0.5 to 1.5.
