Meeting 2024 TMS Annual Meeting & Exhibition
Symposium An Atoms to Autos Approach for Materials Innovations for Lightweighting: An LMD Symposium in Honor of Anil K. Sachdev
Presentation Title The Metallurgy and Design of Alloys for Aerospace Structures – A Historical Perspective
Author(s) Krishnan K. Sankaran
On-Site Speaker (Planned) Krishnan K. Sankaran
Abstract Scope Alloys with optimum combinations of properties such as density, strength, durability, damage tolerance and corrosion resistance continue to be designed and inserted in aerospace systems. Remarkably, these alloys of increasing microstructural complexity developed over many decades are based on narrow composition ranges using a limited number of principal elements and alloying additions. Alloy design is essentially microstructure design. Using alloys based on aluminum , titanium, iron, and nickel used in commercial systems, this presentation will discuss their evolution by means of innovative alloying and processing strategies to produce complex, hierarchical microstructures in a variety of product forms. Among the many examples that will be given are the use of alloying elements to alter the matrix substructure, enhance precipitation kinetics , expand the processing space for ease of manufacturing, etc. These have also formed the basis for a graduate level course on the metallurgy and design of alloys currently being taught.
