Method for making a compositionally graded gas turbine disk |
摘要 |
<p>A compositionally graded gas turbine disk is made by placing a cylindrically symmetric slip case (86) concentrically into an interior (82) of a cylindrically symmetric outer container (80). A first nickel-base superalloy powder is loaded into a radially inner first portion (88) of the interior (82) and a second nickel-base superalloy powder is loaded into a radially outer second portion (90) of the interior (82). The slip case (86) is removed so that the first nickel-base superalloy powder and the second nickel-base superalloy powder contact in the transition region (32) and form a non-compacted powder mass (100). The non-compacted powder mass (100) is processed into a gas turbine disk, typically by compacting the non-compacted powder mass (100) to form a compacted powder mass, and thereafter heat treating the compacted powder mass.</p> |
