Title (EN) POLYCRYSTALLINE COMPACTS INCLUDING METALLIC ALLOY COMPOSITIONS IN INTERSTITIAL SPACES BETWEEN GRAINS OF HARD MATERIAL, CUTTING ELEMENTS AND EARTH-BORING TOOLS INCLUDING SUCH POLYCRYSTALLINE COMPACTS, AND RELATED METHODS
(FR) COMPACTS POLYCRISTALLINS COMPRENANT DES COMPOSITIONS D'ALLIAGE MÉTALLIQUE DANS DES ESPACES INTERSTITIELS ENTRE DES GRAINS DE MATÉRIAU DUR, ÉLÉMENTS DE COUPE ET OUTILS DE FORAGE COMPRENANT CES COMPACTS POLYCRISTALLINS, ET PROCÉDÉS ASSOCIÉS
Abstract: front page image
(EN)Polycrystalline compacts include a polycrystalline material comprising a plurality of inter-bonded grains of hard material, and a metallic material disposed in interstitial spaces between the inter-bonded grains of hard material. At least a portion of the metallic material comprises a metal alloy that includes two or more elements. A first element of the two or more elements comprises at least one of cobalt, iron, and nickel. A second element of the two or more elements comprises at least one of dysprosium, yttrium, terbium, gadolinium, germanium, samarium, neodymium, and praseodymium. The metal alloys may comprise eutectic or near-eutectic compositions, and may have relatively low melting points. Cutting elements and earth-boring tools include such polycrystalline compacts. Methods include the formation of such polycrystalline compacts, cutting elements, and earth-boring tools.
(FR)L'invention concerne des compacts polycristallins qui comprennent un matériau polycristallin comprenant une pluralité de grains interconnectés de matériau dur, et un matériau métallique disposé dans les espaces interstitiels entre les grains interconnectés de matériau dur. Au moins une partie du matériau métallique comprend un alliage de métal qui comprend deux éléments ou plus. Un premier élément de ces deux éléments ou plus comprend au moins un élément parmi le cobalt, le fer et le nickel. Un deuxième élément de ces deux éléments ou plus comprend au moins un élément parmi le dysprosium, l'yttrium, le terbium, le gadolinium, le germanium, le samarium, le néodymium et le praséodymium. Les alliages de métaux peuvent comprendre des compositions eutectiques ou quasi-eutectiques, et peuvent présenter des points de fusion relativement bas. Les éléments de coupe et les outils de forage comprennent ces compacts polycristallins. Les procédés comprennent la formation de ces compacts polycristallins, éléments de coupe et outils de forage.
