Mechanical and Microstructure Properties on Al-Cu Joint processed by Friction Stir Welding: The effect of Tilt Angle Tool

摘要

The tilt angle tool on Aluminum A5083 and Copper C11000 joint processed by Friction Stir Welding (FSW) was observed in this study. The rotation speed and transverse speed were used as a parameter process for 2500 rpm and 30 mm/min, respectively. The tensile test and microstructure observation were carried out to determine the tensile strength and metal flow on Al-Cu joint, respectively. The result shows that the highest tensile strength was in 2° tilt angle tool for 105 MPa. Its fracture surface was more close to Al and formed brittle formation.The metal flows of Al-Cu with 0°and 2° were not homogeneous and formed an agglomeration of Cu particle to Al surface.
