POLYCrystalline COMPACTS INCLUDING METALLIC ALLOY COMPOSITIONS IN INTERSTITIAL SPACES BETWEEN HARD MATERIAL GRAINS, CUTTING ELEMENTS AND PROBING TOOLS, INCLUDING SUCH POLYCrystalline COMPACTS AND CORRELATED METHODS

摘要

compact polycrystals including alloy alloy compositions in interstitial spaces between hard material grains, cutting off probing elements and tools including such compact polycrystals, and related polycrystalline compact methods include a polycrystalline material comprising a plurality of hard material interconnected grains, and a metallic material placed in the interstitial spaces between the grains interconnected by hard material. at least a portion of the metal material comprises a metal alloy comprising two or more elements. A first element of one of the two or more elements is composed of at least one of cobalt, iron and nickel. A second element of two or more elements is composed of at least one of dysprosium, yttrium, terbium, gadolinium, germanium, samarium, neodymium and praseodymium. Metal alloys may comprise eutectic or quasi-eutectic compositions, and may have relatively low melting points. cutting elements and probing tools include such compact polycrystalline. The methods include the formation of such compact polycrystalline, cutting elements and probing tools.
