Patent ID: 7829013

Claim:
A method of forming at least one component of an earth-boring tool, the method comprising: mixing a plurality of hard particles with a powder comprising a binder material to form a mixture, the plurality of hard particles comprising a material selected from boron carbide and carbides or borides of the group consisting of W, Ti, Mo, Nb, V, Hf, Ta, Cr, Zr, Al, and Si, the binder material selected from the group consisting of iron-based alloys, nickel-based alloys, iron and nickel-based alloys, iron and cobalt-based alloys, aluminum-based alloys, copper-based alloys, magnesium-based alloys, titanium-based alloys, cobalt-based alloys, commercially pure aluminum, commercially pure copper, commercially pure magnesium, commercially pure titanium, commercially pure iron and commercially pure nickel; pressing the mixture to form a green part; and at least partially sintering the green part to form at least one component of an earth-boring tool.
