Elevated-Temperature Al Alloys for Aircraft Structure
- 24 Downloads
Elevated-temperature powder metallurgy (P/M) aluminum alloys are being developed to replace titanium aircraft structure materials for operation in the 300–600°F temperature range. Typical mechanical properties ofP/M Al−Fe−Ce and Al−Fe−V−Si alloys are superior to those of conventional materials, and cost savings of fifty to seventy percent have been projected for these alloys which can be fabricated and processed using methods similar to those used in the production of conventional aluminum.
