description: This work is devoted to the study of strengthening phases in thermally strengthened aluminum alloys during pulsed friction welding with mixing, as well as the influence of pulse parameters on the structure and mechanical properties of welded butt joints. Metallographic studies revealed changes in the macro - and microstructure in various zones of the weld under the influence of pulses of different strengths and frequencies. The influence of these parameters on mechanical properties of the welded joint. X-ray energy-dispersive element analysis, scanning and transmission electron microscopy, and differential scanning calorimetry have been used to study the evolution of strengthening phases in the aluminum alloys under study after friction-stir welding and pulsed friction-stir welding at various parameters. Based on the results obtained, the relationships between microstructure and evolution were formulated strengthening phases and mechanical properties of welded joints.
