Aluminum alloys have been widely studied and used for various structural applications since the early 1900s. New developments have produced aluminum lithium (Al-Li) alloys, which offer advantageous properties, including improved fatigue crack growth resistance, superior specific strength, high fracture toughness, density reduction, stiffness increase, and greater corrosion resistance. Friction stir welding (FSW) has gained a great deal of attention from various industries looking for a more effective technology to join lightweight metals. FSW is an attractive joining method due to the multiple environmental, metallurgical, and adaptability advantages that it offers. While FSW has been successfully validated and studied for traditional aluminum alloys, there is a need for knowledge in applying FSW to join AL-Li alloys. A comprehensive study was performed on the microstructure and mechanical performance of AL-Li 2099 under static and cyclic loading. Results were compared to the performance of traditional alloys.
