    Abstract: Methods of forming cutter assemblies for use on earth-boring tools include sintering a cone structure to fuse one or more cutting elements thereto. In some embodiments, one or more green, brown, or fully sintered cutting elements may be positioned on a green or brown cone structure prior to sintering the cone structure to a final density. Cutter assemblies may be formed by such methods, and such cutter assemblies may be used in earth-boring tools such as, for example, earth-boring rotary drill bits and hole openers.

    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.

    Abstract: Methods of forming earth-boring rotary drill bits by forming and joining two or less than fully sintered components, by forming and joining a first fully sintered component with a first shrink rate and forming a second less than fully sintered component with a second sinter-shrink rate greater that that of the first shrink rate of the first fully sintered component, by forming and joining a first less than fully sintered component with a first sinter-shrink rate and by forming and joining at least a second less than fully sintered component with a second sinter-shrink rate less than the first sinter- shrink rate. The methods include co-sintering a first less than fully sintered component and a second less than fully sintered component to a desired final density to form at least a portion of an earth-boring rotary drill bit which may either cause the first less than fully sintered component and the second less than fully sintered component to join or may cause one of the first less than fully sintered component and the second less than fully sintered component to shrink around and at least partially capture the other less than fully sintered component. Earth-boring rotary drill bits are formed using such methods.
