  • Patent number: 10487589
    Abstract: An earth-boring tool includes a bit body and an actuator coupled to the bit body. The actuator includes at least one shape memory material configured to transform from a first shape to a second shape to move a bearing pad or a cutting element with respect to the bit body in response to a stimulus. A transformation from the first shape to the second shape includes a phase change from a first solid phase to a second solid phase. A depth-of-cut limiter includes a bearing element and at least one shape memory material coupled to the bearing element. A method of forming or servicing a wellbore includes rotating an earth-boring tool within a wellbore, applying a stimulus to an actuator to convert at least one shape memory material from a first shape to a second shape, and continuing to rotate the earth-boring tool within the wellbore after applying the stimulus.

  • Patent number: 10280479
    Abstract: An earth-boring tool includes a tool body, at least one cutting element, and a retaining member comprising a shape memory material (e.g., alloy, polymer, etc.) located between a surface of the tool body and a surface of the cutting element. The shape memory material is configured to transform, responsive to application of a stimulus, from a first solid phase to a second solid phase. The retaining member comprises the shape memory material in the second solid phase, and at least partially retains the at least one cutting element adjacent the tool body. The shape memory material may be trained in a first phase to a first shape, and trained in a second phase to a second shape. The retaining member may be at least partially within a cavity in the first phase, then transformed to the second phase to apply a force securing the cutting element to the tool body.
