The Effect of Process Parameters on Microstructural and Mechanical Properties of Friction Stir Welded Age Hardenable Aluminium Alloy

Abstract

FSW has become the most effective technology in solving problems that have reached the profiled sheets with the continuation of material, particularly in the aerospace industry, with the use of different joining techniques that require high ductility and tensile strength. Current study, FS weldments AA6061-T6 were successfully obtained with varying processing parameters and were mechanically and metallurgically characterized. This paper illustrates macrostructure analysis, influence of tool geometry and process parameters, Fractography analysis microstructure analysis, microhardness of aluminium alloy AA6061-T6.
