摘要

A study of the high-strength titanium alloy VT23 (Ti-6Al-5V-2Mo-1Cr-1Fe) after its friction stir welding and friction stir processing is performed at different parameters. The metallographic research shows some microstructural changes in the metal after this friction stir technological processes. The mechanical tests of the weld joints and processed material show a decrease in the ultimate strength. The XRD analysis confirms the phase changes in the high-strength titanium alloy.
