Properties of Aluminium-Lithium Alloys for Aerospace Applications- A Comprehensive Review

Abstract: A different combination of alloys has been experimented in the current trend, but some combinations are more significant than others, like Aluminum- Lithium alloy, which is highly known for its applications in the aviation and aerospace domain. The properties of this alloy urge for various research findings over it. This paper sums up major properties for the selection of material incorporates its tensile properties and its effects, fracture mechanism, most importantly fatigue life cycle, grain size, and its morphology, etc. The study over different grades of Al-li alloy are summarized along with its applications.
