An Experimental Investigation on Mechanical Properties and Microstructure of Friction Stir Welding of AA5052
Abstract:
The aim of this project is to study the micro-structural and mechanical property changes during friction stir welding [FSW] with a special focus on AA5052. The objective of this project is to experimentally investigate the influence of tool pin profiles (straight cylinder, fluted cylinder and pentagonal cylinders) and welding input parameters (rotational speed and traverse speed) on microstructure and mechanical properties (tensile strength, hardness) of AA5052 Al in FSW process. The detailed micro-structural analyses are carried out on the base metal and welded zone (nugget zone), Thermo mechanically affected zone and heat affected zone. The mechanical properties such as, tensile and hardness are studied before and after FSW process.
