Abstract:
The present invention includes consolidated hard materials, methods for producing them, and industrial drilling and cutting applications for them. A consolidated hard material may be produced using hard particles such as B4C or carbides or borides of W, Ti, Mo, Nb, V, Hf, Ta, Zr, and Cr in combination with an iron-based, nickel-based, nickel and iron-based, iron and cobalt-based, aluminum-based, copper-based, magnesium-based, or titanium-based alloy for a binder material. Commercially pure elements such as aluminum, copper, magnesium, titanium, iron, or nickel may also be used for the binder material. The mixture of the hard particles and the binder material may be consolidated at a temperature below the liquidus temperature of the binder material using a technique such as rapid omnidirectional compaction (ROC), the CERACON™ process, or hot isostatic pressing (HIP). After sintering, the consolidated hard material may be treated to alter its material properties.
