摘要： Geometric compensation techniques are used to improve the accuracy by which features may be located on drill bits formed using particle compaction and sintering processes. In some embodiments, a positional error to be exhibited by at least one feature in a less than fully sintered bit body upon fully sintering the bit body is predicted and the at least one feature is formed on the less than fully sintered bit body at a location at least partially determined by the predicted positional error. In other embodiments, bit bodies of earth-boring rotary drill bits are designed to include a design drilling profile and a less than fully sintered bit body is formed including a drilling profile having a shape differing from a shape of the design drilling profile. Less than fully sintered bit bodies of earth-boring rotary drill bits are formed using such methods.

摘要： 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.

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.
