en Research Paper Research Paper Novelty: Most of the open literature research has focused on the microstructural evolution and mechanical properties of AA2050 alloy. Also, a significant study discusses the corrosion behavior of AA2050 alloy based on immersion and electrochemical characteristics. The influence of heat treatment on the microstructure and mechanical properties of friction stir processed AA2050 alloy is scarcely discussed in the open literature. The hot salt corrosion characteristics of friction stir processed AA2050 seldom exists in the available literature. This study concentrates on microhardness, tensile strength, and corrosion properties of friction stir processed AA2050. Also, the work focuses on the influence of artificial aging on the microhardness, and tensile strength of the friction stir processed AA2050.<br> <br> &nbsp; Friction stir processing,Al-Cu-Li alloy,Microstructure,Heat Treatment,Corrosion 1 14 http://ijmse.iust.ac.ir/browse.php?a_code=A-10-4344-1&slc_lang=en&sid=1 Sandeep Ramasamy Periasamy rpsandeep98@gmail.com 1800319475328460017359 1800319475328460017359 No Department of Mechanical Engineering, Amrita School of Engineering, Coimbatore, Amrita Vishwa Vidyapeetham, India.
