ABSTRACT:
Methods for forming bodies of earth-boring drill bits and other tools include milling a plurality of hard particles and a plurality of particles comprising a matrix material to form a mill product comprising powder particles, separating the particles into a plurality of particle size fractions. Some of the particles from the fractions may be combined to form a powder mixture, which may be pressed to form a green body. Additional methods include mixing a plurality of hard particles and a plurality of particles comprising a matrix material to form a powder mixture, and pressing the powder mixture with pressure having an oscillating magnitude to form a green body. In yet additional methods a powder mixture may be pressed within a deformable container to form a green body and drainage of liquid from the container is enabled as the powder mixture is pressed.
