Abstract
A method of joining a component, such as a cutting element, to another component or body of an earth-boring tool, according to embodiments of the present disclosure, includes disposing a third-body structure, which may comprise a braze material, between a surface of the component and a surface of the another component of the earth-boring tool. The component to be joined is then rotated relative to the surface of the another component to generate frictional heat in the third-body structure and to at least plasticize material of the third-body structure. After the rotation, the plasticized material of the third-body structure is compressed between the surfaces and then allowed to solidify, which bonds the component to the another component without deforming either the component or the another component.
