Abstract: A compositionally graded gas turbine disk is made by preparing a rotationally symmetric radially inner segment of a gas turbine disk preform, rotating the inner segment about a central axis, spray applying a radially outer-segment material onto the radially inner segment as it rotates about the central axis, preferably achieving a gradual transition in composition, and thereafter further processing the gas turbine disk preform to produce the compositionally graded gas turbine disk.

Abstract: A compositionally graded gas turbine disk is made by placing a cylindrically symmetric slip case concentrically into an interior of a cylindrically symmetric outer container. A first nickel-base superalloy powder is loaded into a radially inner first portion of the interior and a second nickel-base superalloy powder is loaded into a radially outer second portion of the interior. The slip case is removed so that the first nickel-base superalloy powder and the second nickel-base superalloy powder contact in the transition region and form a non-compacted powder mass. The non-compacted powder mass is processed into a gas turbine disk, typically by compacting the non-compacted powder mass to form a compacted powder mass, and thereafter heat treating the compacted powder mass.
