Abstract

The effect of the high-speed impact of a shaped-charge jet on the structure and strength of commercially pure VT1 titanium and VT22, VT3-1, and PT-3V titanium alloys is studied in comparison with AK6 aluminum alloy and Br OTsS bronze. The strength is characterized in terms of the microhardness. The microhardness versus structure is analyzed in the near-surface layer along the channel formed by the shaped-charge jet. The results obtained are used to qualitatively estimate the structural modification, type of fracture, and strength of targets made of the alloys.
