    Abstract: 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.

    Abstract: Methods of forming a polycrystalline element comprise disposing a first plurality of particles comprising a superabrasive material, a second plurality of particles comprising the superabrasive material, and a catalyst material in a mold. The first and second pluralities of particles are sintered to form a polycrystalline table comprising a first region having a first permeability and a second region having a second, greater permeability. Catalyst material is at least substantially removed from the polycrystalline table. The polycrystalline table is attached to an end of a substrate, the at least a second region being interposed between the first region and the substrate. Polycrystalline elements comprise a substrate. A polycrystalline table comprising a superabrasive material and having a first region exhibiting a first permeability and at least a second region exhibiting a second, greater permeability is attached to an end of the substrate.
