The Development of Aluminum-Lithium Alloys.

Abstract

Aluminum-lithium based alloys have shown promise as high strength, high modulus, low density alloys, but suffer from low toughness levels currently unacceptable in aerospace design. The present study was directed toward increasing the fracture toughness of such alloys in sheet form, primarily through alloying. Attempts to increase fracture toughness were made through modification of the fracture-controlling Al3Li precipitate, addition of dispersoid-forming elements, and the use of coprecipitation of other phases.
