Book Description
Dispersion-strengthened powder metallurgy aluminum alloys are being developed for structural applications up to 616 K (650°F). This research is being conducted under Air Force Wright Aeronautical Laboratories/Materials Laboratory Contract No. F33615-81-C-5096. The Lockheed-California Co. is the prime contractor with the Aluminum Company of America (Alcoa) and Pratt and Whitney Aircraft participating as subcontractors. The current alloy development has been directed towards the goal of producing high-strength/high-stiffness alloys with properties competitive to those of Ti-6Al-4V on a density-compensated basis. Alcoa has been developing the Al-Fe-Ce alloy system and Pratt and Whitney the Al-Fe-Mo alloy system. The second iteration of alloy development is presented. Mechanical property behavior of each rectangular extruded alloy was evaluated. The testing included room-temperature and elevated-temperature tension, fracture toughness, creep, and elevated-temperature stability tests. The Al-Fe-Ce alloys met or exceeded most of the program goals, while the Al-Fe-Mo alloys nearly achieved all of the goals. Achievement of the target properties provides a 15% weight savings for airframe structures and up to 35% weight savings for engine components.

Oxide Dispersion Strengthened Refractory Alloys
Author: Anshuman Patra
Publisher: CRC Press
ISBN: 1000580555
Category : Technology & Engineering
Languages : en
Pages : 199
Book Description
Refractory metals such as W, Mo, Ta, Nb, and Re have immense potential for application in plasma-facing materials in nuclear reactors, defense materials, aviation counterweights, heating elements in furnaces, and so forth. This book presents a wide perspective of oxide dispersion strengthened refractory alloys fabrication and critical properties. It provides a comprehensive road map for an appropriate basis for alloy design, process parameter selection, fabrication route, and deformation behavior for oxide dispersion strengthened refractory alloys. It further covers achievement of application-oriented properties and critical process-regulating parameters for development of sustainable materials. Features: Covers development of oxide dispersion strengthened sustainable material to withstand high-temperature environments Describes stimulating application-oriented final mechanical properties Illustrates fabrication of alloys through effective route to achieve desired properties Presents in-depth explanation of deformation behavior at ambient and high temperatures Explores critical applications of the alloys in nuclear reactors, defense, and aviation sectors Oxide Dispersion Strengthened Refractory Alloys will be of interest to graduate students and researchers in high-temperature materials, mechanics, metallurgy, powder metallurgy, and physical metallurgy.
