Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Polycrystalline compacts include hard polycrystalline materials comprising in situ nucleated smaller grains of hard material interspersed and inter-bonded with larger grains of hard material. The average size of the larger grains may be at least about 250 times greater than the average size of the in situ nucleated smaller grains. Methods of forming polycrystalline compacts include nucleating and catalyzing the formation of smaller grains of hard material in the presence of larger grains of hard material, and catalyzing the formation of inter-granular bonds between the grains of hard material. For example, nucleation particles may be mixed with larger diamond grains, a carbon source, and a catalyst. The mixture may be subjected to high temperature and high pressure to form smaller diamond grains using the nucleation particles, the carbon source, and the catalyst, and to catalyze formation of diamond-to-diamond bonds between the smaller and larger diamond grains.
