Abstract
A turbine bucket includes an airfoil portion; a platform at radially inner end of the airfoil portion; a shank portion extending radially-inwardly of the platform; and a mounting portion extending radially-inwardly of the shank portion. The shank portion and the mounting portion have at least one axially-extending seal-engaging surface formed as part of a separable, non-integral isolation element that isolates the bucket from forces caused by a near-flow-path seal engaging the at least one axially-extending seal-engaging surface.
