摘要：

In this research work, some important investigations were carried out to find out the changes in the macro, microstructures and mechanical properties of the Aluminum 2024 alloy. It is clearly understood through experimentation that friction stir welded components exhibits remarkable morphological and mechanical properties with proper selection of tool geometry, rotational speeds and feeds which greatly influence the weld quality and the weld strength. The present trialing uses taper cylindrical tool pin profile with different process parameter values under constant axial load of 3 kN were considered. Further the study reveals that tool rotational speed of 1000 rpm, feed rate of 30 mm/min are best suitable for the selected work material which produces tensile strength of 300MPa and high yield strength of 280MPa with parent metal along with marginal tunnel defect.
