摘要： Methods of forming earth-boring rotary drill bits by forming and joining two 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.

摘要： Partially formed earth-boring rotary drill bits comprise a first less than fully sintered particle-matrix component having at least one recess, and at least a second less than fully sintered particle-matrix component disposed at least partially within the at least one recess. Each less than fully sintered particle-matrix component comprises a green or brown structure including compacted hard particles, particles comprising a metal alloy matrix material, and an organic binder material. The at least a second less than fully sintered particle-matrix component is configured to shrink at a slower rate than the first less than fully sintered particle-matrix component due to removal of organic binder material from the less than fully sintered particle-matrix components in a sintering process to be used to sinterbond the first less than fully sintered particle-matrix component to the first less than fully sintered particle-matrix component. Earth-boring rotary drill bits comprise such components sinterbonded together.

摘要： Cutting elements for use in earth-boring applications include a substrate, a transition layer, and a working layer. The transition layer and the working layer comprise a continuous matrix phase and a discontinuous diamond phase dispersed throughout the matrix phase. The concentration of diamond in the working layer is higher than in the transition layer. Earth-boring tools include at least one such cutting element. Methods of making cutting elements and earth-boring tools include mixing diamond crystals with matrix particles to form a mixture. The mixture is formulated in such a manner as cause the diamond crystals to comprise about 50% or more by volume of the solid matter in the mixture. The mixture is sintered to form a working layer of a cutting element that is at least substantially free of polycrystalline diamond material and that includes the diamond crystals dispersed within a continuous matrix phase formed from the matrix particles.

摘要： A reactive foil is used to assemble the components of rock bit cutters and to affix cutting elements to rock bit bodies. A small pulse of localized energy ignites the foil in a fraction of a second to deliver the necessary amount of heat energy to flow solder or braze and form a strong, true metallic joint. The reaction in the foil may be activated using optical, electrical, or thermal sources.

摘要： A method for conducting nondestructive internal inspection of a rotary drill bit used for drilling subterranean formations comprises communicating ultrasonic waves into a drill bit and detecting ultrasonic waves that are reflected by at least a portion of the drill bit. In some embodiments, the waves may be directed into the drill bit from within a longitudinal bore thereof. Reflected waves also may be detected from within the bore. The methods may be used to develop threshold acceptance criteria for classifying drill bits as acceptable or unacceptable to prevent catastrophic failures of drill bits during use. Systems and apparatuses are disclosed for conducting nondestructive ultrasonic inspection of a drill bit used for drilling subterranean formations. The systems and apparatuses may comprise an ultrasonic probe configured for insertion within an internal longitudinal bore of a drill bit. Drill bits are disclosed that are configured to facilitate nondestructive ultrasonic inspection thereof.
