“…Because of these aspects, Li is the optimum metallic element for Al alloys. Compared with traditional Al alloys, Al-Li alloys exhibit better stiffness, strength, and fracture toughness and a lower density [12] , [13] , [14] . Additionally, the fracture toughness of Al-Li alloys at cryogenic temperatures is higher than that of traditional Al alloys.…”

“…Most of these alloys are developed on the basis of the Al-Li-Cu system. In Russia, in VIAM, there also developed and introduced into practice the high-strength alloys 1461, 1469 [30][31][32][33][34], which are an alternative to the main structural alloys-of the Al-Cu-Mg and Al-Zn-Mg-Cu systems-of the types 2X24, 7075, and V95 [13,31]. Chronological analysis of the development of commercial alloys reveals the fundamental principles of their production.…”

An overview of modern material science problems is presented for ultralightweight high-modulus commercial Al-Li-based alloys in historical retrospect. Numerous particular examples of the Soviet and Russian aviation whose various designs were made of these alloys confirm their successful innovative potential. The key regularities of multicomponent alloying are discussed for the master alloys and modern commercial Al-Li-based alloys of the latest generation; the features typical of their microstructures, phase composition, and properties formed during aging are analyzed. The main mechanisms of phase formation are generalized for standard thermal and thermomechanical treatments. Recent original achievements have been obtained in designing of unique structural and phase transformations in these commercial alloys by means of methods of severe plastic deformations followed by heat treatment and storage. Using the example of three Russian commercial alloys of last generation, the basic principles of creating and controlling an ultrafine-grained structure, the origin and growth of stable nanophases of various types and chemical composition that determine the physicomechanical properties of alloys are established.

“…Al alloys other phrases, this Li added to Al is the optimum alloy and exhibits better stiffness, fracture toughness at cryogenic temperature. This Al-Li has higher resistance to fatigue growth and resistance at a higher level than traditional Al-Alloy at this cryogenic temperature [4][5][6][7][8][9]. This alloy can be utilized for numerous applications owing to its superior properties [10].…”

Aluminium (Al)-Lithium (Li) alloys have found widespread applications in aerospace and military domains. Primarily, they are found to have low density, leading to weight savings and several economic considerations. The paper explores the historical development of Al-Li alloys across distinct generations, highlighting their evolution. It also delves into the diverse applications of Al-Li alloys in aerospace and military domains. A concise discussion of the mechanical behaviour and tensile strengths is presented across the first, second, and third generations of Al-Li alloys. This review includes a discussion on microstructural investigation, emphasizing metallurgical factors such as increased efficiency, various precipitate phases, and intergranular features. Weldability and tribological properties of Al-Li alloys, with a specific emphasis on the corrosion aspects of these alloys are discussed. Furthermore, the review assesses the future development and manufacturing flexibility of Al-Li Metal Matrix Composites. In summary, this comprehensive review consolidates insights into the utilization, evolution, and characteristics of Al-Li Metal Matrix Composites, providing valuable information for researchers and practitioners aiming to enhance the performance of these alloys in aerospace applications.
