Microstructure and Mechanical Properties of Dissimilar Al – Cu Joints Formed by Friction Stir Welding

  • Published:
Metal Science and Heat Treatment Aims and scope

Friction-stir-welded joints of commercial-purity copper and aluminum alloy AMg5 are studied. The effect of the process parameters on the microstructure and mechanical properties of the joints is analyzed. The results of temperature measurements during the welding made with the help of thermocouples are presented. A mathematical model is suggested for computing the temperature field of a weld. The computed and experimental data are compared.
