The Influence of Process Parameters on the Mechanical Properties of Friction Stir-Welded Dissimilar Aluminium Alloys AA2219 and AA7068

A practical solution is friction stir welding (FSW) of heterogeneous alloys in industrial applications. The welded joint’s mechanical strength has been improved by combining two different (AA2219 and AA7068). focus this study was on stir-welded metals’ microhardness material properties. It possible to work with either hot or cold aluminium alloy, as it heat treatable. Revitalizing precipitation hardening follow the treatment. joints’ hardness assessed several locations. Different tensile characteristics are compared. According stress-strain curve, FSW settings’ properties were spread throughout flow. In terms tool profiles, cylindrical threaded profile critical. One-third efficiency due it. 195 MPa reached pin profiled tool. a new study, researchers discovered that threads have faster rotary motion, transversal, D/d speeds. provided highest superior other materials. This phase characterization included measurements hardness.
