摘要

The paper investigates the production of multicomponent composite material based on titanium alloy Grade 2 containing copper, nickel, tungsten and zirconium. The obtained composite materials are characterized by a nonuniform distribution of intermetallic particles even after four movements of the tool in the processing direction. The stir zone is a region affected by the tool after its pin penetration during processing and usually has several concentric rings. The material microstructure after friction stir processing has three zones. First is the stir zone, i.e., a region affected by the tool after its pin penetration during processing and usually has several concentric rings. Second is the flow arm (shoulder) zone of the material dragged by the tool shoulder from the retreating to the advancing side of the weld. And third, the thermo-mechanically affected zone forming on both sides the stir zone. During stir processing, the metal flows around the tool and contributes to the particle distribution in the stir zone with a separation of added powders due to their different intermixing with the metal matrix.
