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.

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 for forming cutting elements comprising polycrystalline materials, methods for forming polycrystalline compacts for cutting elements of a drilling tool, method for forming polycrystalline diamond compacts, and resulting polycrystalline compacts and cutting elements are disclosed. Grains of a hard material are introduced to a press and subjected to a high pressure, high temperature (HPHT) process to sinter the grains. The system conditions (i.e., temperature and pressure) are then adjusted past a phase or state change point, after which, at least one of the system conditions is held during an anneal stage before the system conditions are adjusted to final levels. The resulting compacts and cutting elements may therefore include inter-granularly bonded hard material grains with a more stable microstructure (e.g., less stressed microstructure) than a polycrystalline compact and cutting element formed without an anneal stage during the HPHT process.
