摘要： Methods for forming cutting elements, methods for forming polycrystalline compacts, and related polycrystalline compacts are disclosed. Grains of a hard material are subjected to a high-pressure, high-temperature process to form a polycrystalline compact. Inclusion of at least one relatively quick spike in system pressure or temperature during an otherwise plateaued temperature or pressure stage accommodates formation of inter-granular bonds between the grains. The brevity of the peak stage may avoid undesirable grain growth. Embodiments of the methods may also include at least one of oscillating at least one system condition (e.g., pressure, temperature) and subjecting the grains to ultrasonic or mechanical vibrations. A resulting polycrystalline compact may include a high density of inter-granularly bonded hard material with a minimized amount of catalyst material, and may provide improved thermal stability, wear resistance, toughness, and behavior during use of a cutting element incorporating the polycrystalline compact.

摘要： Methods of forming cutting elements for earth-boring tools include providing a barrier material between a first powder and a second powder each comprising diamond grains, and subjecting the powders and barrier material to high temperature and high pressure conditions to form polycrystalline diamond material. The formation of the polycrystalline diamond material is catalyzed, and catalytic material may be hindered from migrating across the layer of barrier material. Cutting elements for use in earth-boring tools include a barrier material disposed between a first layer of polycrystalline diamond material and a second layer of polycrystalline diamond material. Earth-boring tools include one or more such cutting elements for cutting an earth formation.

摘要： Cutting elements for earth-boring tools may generate a shear lip at a wear scar thereon during cutting. A diamond table may exhibit a relatively high wear resistance, and an edge of the diamond table may be chamfered, the combination of which may result in the formation of a shear lip. Cutting elements may comprise multi-layer diamond tables that result in the formation of a shear lip during cutting. Earth-boring tools include such cutting elements. Methods of forming cutting elements may include selectively designing and configuring the cutting elements to form a shear lip. Methods of cutting a formation using an earth-boring tool include cutting the formation with a cutting element on the tool, and generating a shear lip at a wear scar on the cutting element. The cutting element may be configured such that the shear lip comprises diamond material of the cutting element.

摘要： Cutting elements for use in earth-boring applications include a substrate, a transition layer, and a working layer. The transition layer and the working layer comprise a continuous matrix phase and a discontinuous diamond phase dispersed throughout the matrix phase. The concentration of diamond in the working layer is higher than in the transition layer. Earth-boring tools include at least one such cutting element. Methods of making cutting elements and earth-boring tools include mixing diamond crystals with matrix particles to form a mixture. The mixture is formulated in such a manner as cause the diamond crystals to comprise about 50% or more by volume of the solid matter in the mixture. The mixture is sintered to form a working layer of a cutting element that is at least substantially free of polycrystalline diamond material and that includes the diamond crystals dispersed within a continuous matrix phase formed from the matrix particles.
