Popis: |
A study was conducted to optimize the major element chemistry of powder metallurgy (PM) alloys for the challenging goals of a High Speed Civil Transport (HSCT) application. Two iterations were performed. Subscale heats of experimental powders were atomized, consolidated by extrusion, isothermally forged, and supersolvus heat treated. Key relationships were identified between alloying elements resulting in the identification of an optimized alloy composition. The final alloy showed significant improvements in creep and in hold time crack growth compared to state-of-the art commercial alloys. |
