摘要： Methods of forming at least a portion of an earth-boring tool include providing particulate matter comprising a hard material in a mold cavity, melting a metal and the hard material to form a molten composition comprising a eutectic or near-eutectic composition of the metal and the hard material, casting the molten composition to form the at least a portion of an earth-boring tool within the mold cavity, and adjusting a stoichiometry of at least one hard material phase of the at least a portion of the earth-boring tool. Methods of forming a roller cone of an earth-boring rotary drill bit include forming a molten composition, casting the molten composition within a mold cavity, solidifying the molten composition to form the roller cone, and converting an eta-phase region within the roller cone to at least one of WC and W2C.

摘要： A composite includes a porous matrix that includes a molybdenum-silicon-boron (Mo—Si—B) alloy that has a plurality of pores with a lubricant in contact with the Mo—Si—B alloy, a hydrophobic compound in contact with the Mo—Si—B alloy, or a combination thereof. A method for preparing a porous composite includes disposing a porous matrix comprising a Mo—Si—B alloy on a substrate, the Mo—Si—B alloy comprising a plurality of pores; disposing a lubricant on a surface of the porous matrix; and disposing a hydrophobic compound on a surface of the porous matrix to form the porous composite.

摘要： Methods of forming at least a portion of an earth-boring tool include providing particulate matter including a hard material in a mold cavity, melting a metal and the hard material to form a molten composition comprising a eutectic or near-eutectic composition of the metal and the hard material, casting the molten composition to form the at least a portion of an earth-boring tool within the mold cavity, and providing an inoculant within the mold cavity. Methods of forming a roller cone of an earth-boring rotary drill bit include forming a molten composition, casting the molten composition within a mold cavity, solidifying the molten composition to form the roller cone, and controlling grain growth using an inoculant as the molten composition solidifies. Articles including components of earth-boring tools are fabricated using such methods.

摘要： Methods of forming at least a portion of an earth-boring tool include providing at least one insert in a mold cavity, providing particulate matter in the mold cavity, melting a metal and a hard material to form a molten composition, and casting the molten composition. Other methods include coating at least one surface of a mold cavity with a coating material having a composition differing from a composition of the mold, melting a metal and a hard material to form a molten composition, and casting the molten composition. Articles comprising at least a portion of an earth-boring tool include at least one insert and a solidified eutectic or near-eutectic composition including a metal phase and a hard material phase. Other articles include a solidified eutectic or near-eutectic composition including a metal phase, a hard material phase and a coating material in contact with the solidified eutectic or near-eutectic composition.
