The Structure and Properties of Dispersed Aluminium Composite Compounds Made by Welding Friction with Mixing

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.
