Abstract: Methods of forming bit bodies for earth-boring bits include assembling green components, brown components, or fully sintered components, and sintering the assembled components. Other methods include isostatically pressing a powder to form a green body substantially composed of a particle-matrix composite material, and sintering the green body to provide a bit body having a desired final density. Methods of forming earth-boring bits include providing a bit body (52) substantially formed of a particle-matrix composite material and attaching a shank to the body. The body is provided by pressing a powder to form a green body and sintering the green body. Earth-boring bits include a unitary structure substantially formed of a particle-matrix composite material . The unitary structure includes a first region configured to carry cutters and a second region that includes a threaded pin. Earth-boring bits include a shank attached directly to a body substantially formed of a particle-matrix composite material.

Abstract: Methods for welding a particle-matrix composite body (120) to another body (154) and repairing particle-matrix composite bodies (120) are disclosed. Additionally, earth-boring tools (110) having a joint that includes an overlapping root portion and a weld groove having a face portion with a first bevel portion and a second bevel portion are disclosed. In some embodiments, a particle-matrix bit body (120) of an earth-boring tool (100) may be repaired by removing a damaged portion, heating the particle-matrix composite bit body (120), and forming a built-up metallic structure thereon. In other embodiments, a particle-matrix composite body (120) may be welded to a metallic body (154) by forming a joint, heating the particle-matrix composite body (120), melting a metallic filler material forming a weld bead and cooling the welded particle-matrix composite body (120), metallic filler material and metallic body (154) at a controlled rate.

Abstract: Earth-boring tools for drilling subterranean formations include a particle-matrix composite material comprising a plurality of silicon carbide particles dispersed throughout a matrix material, such as, for example, an aluminum or aluminum-based alloy. In some embodiments, the silicon carbide particles comprise an ABC-SiC material. Methods of manufacturing such tools include providing a plurality of silicon carbide particles within a matrix material. Optionally, the silicon carbide particles may comprise ABC-SiC material, and the ABC-SiC material may be toughened to increase a fracture toughness exhibited by the ABC-SiC material. In some methods, at least one of an infiltration process and a powder compaction and consolidation process may be employed.

Abstract: Methods of forming earth-boring rotary drill bits (50) include providing a bit body (52), providing a shank(70) that is configured for attachment to a drill string, and attaching the shank to the bit body. Providing a bit body includes providing a green powder component having a first region (54) having a first composition and a second region (56) having a second, different composition, and at least partially sintering the green powder component. Other methods include providing a powder mixture, pressing the powder mixture to form a green component, and sintering the green component to a final density. A shank(70) is provided that includes an aperture (72), and a feature(60) is machined in a surface of the bit body. The aperture is aligned with the feature, and a retaining member (80) is inserted through the aperture. An earth-boring bit includes a bit body comprising a particle-matrix composite material including a plurality of hard particles dispersed throughout a matrix material. A shank is attached to the bit body using a retaining member.
