Abstract
An earth-boring tool includes a tool body having an aperture therein defining a nozzle port, a nozzle or nozzle assembly disposed in the nozzle port, and a shape memory material disposed adjacent a surface of at least one component of the nozzle or nozzle assembly. The shape memory material retains at least one component of the nozzle or nozzle assembly by a threadless connection. The threadless connection includes mechanical interference between the shape memory material, the at least one component of the nozzle or nozzle assembly, and the tool body or another component of the nozzle or nozzle assembly. The shape memory material is formulated and configured to transform from a first phase and a first shape upon heating and to transform from a second phase and a second shape upon cooling.
