The use of friction welding with mixing allows to obtain non-defectal compounds of both alloy AL25 and dispersed particles composite aluminum materials. It was found that in addition to changes in the grain structure of the α-Al solid solution, there are changes in the process of the release of particles of intermetallide phases, which can be traced in the morphology, medium size and chemical composition of particles of intermetallide phases of different natures. The change in the morphology of secondary phase particles is due to the difference in thermo mechanical influence in different areas of the formation of the compound when welding friction with mixing.

Copper-aluminium composite heat dissipation components have both the high thermal conductivity of copper and the low density of aluminium. Copper and aluminium are dissimilar materials as they have significant differences in physical and chemical properties, and hence it is not easy to weld them together. In this paper, the joining of copper to aluminium is studied by using the ultrasonic brazing technique. The results show that the copper and aluminium can be connected by ultrasonic brazing, and it is found that the bonding of the copper side interface is the weak link of the entire joint, but the joint strength can still reach 95MPa.
