    摘要： Polycrystalline elements comprise a substrate and a polycrystalline table attached to an end of the substrate. The polycrystalline table comprises a first region of superabrasive material having a first permeability and at least a second region of superabrasive material having a second, lesser permeability, the at least second region being interposed between the substrate and the first region. Methods of forming a polycrystalline element comprise attaching a polycrystalline table comprising a first region of superabrasive material having a first permeability and at least a second region of superabrasive material having a second, lesser permeability to an end of a substrate, the at least a second region being interposed between the first region and the substrate. Catalyst material is removed from at least the first region of the polycrystalline table.

    摘要： Methods and associated tools and components related to generating and obtaining performance data during drilling operations of a subterranean formation is disclosed. Performance data may include thermal and mechanical information related to earth-boring drilling tool during a drilling operation are disclosed. For example, a cutting element of an earth-boring drilling tool may include a substrate with a cutting surface thereon. The cutting element may further include at least one thermistor sensor coupled with the cutting surface, and a conductive pathway operably coupled with the at least one thermistor sensor. The at least one thermistor sensor may be configured to vary a resistance in response to a change in temperature. The conductive pathway may be configured to provide a current path through the at least one thermistor sensor in response to a voltage. Other methods, tools and components are provided.

    摘要： Polycrystalline compacts include a hard polycrystalline material comprising first and second regions. The first region comprises a first plurality of grains of hard material having a first average grain size, and a second plurality of grains of hard material having a second average grain size smaller than the first average grain size. The first region comprises catalyst material disposed in interstitial spaces between inter-bonded grains of hard material. Such interstitial spaces between grains of the hard material in the second region are at least substantially free of catalyst material. In some embodiments, the first region comprises a plurality of nanograins of the hard material. Cutting elements and earth-boring tools include such polycrystalline compacts. Methods of forming such polycrystalline compacts include removing catalyst material from interstitial spaces within a second region of a polycrystalline compact without entirely removing catalyst material from interstitial spaces within a first region of the compact.
