Linear Friction Welding of a Commercial Aluminum Alloy


Article Preview

The mechanical properties and microstructure of a solid-phase compound produced by linear friction welding (LFW) of commercial Al-4.4%Cu-0.5%Mg-0.4%Mn-0.5%Ag alloy have been studied. The samples of Al-Cu-Mg-Ag alloy were produced by ingot metallurgy and subjected to thermomechanical treatment to get different initial microstructures. It has been shown that the LFW of two rectangular-shaped samples with different microstructures enabled forming a well-done welding joint without macroscopic defects. The LFW samples have shown high mechanical properties. Strength has reached 452 MPa, and plasticity has become not less 15%. The microstructure transformation in the welding joint during plastic deformation and deformation heating at LFW is discussed.
