Plastic deformation of titanium alloy Ti-6Al-4V in a complex stressed state under tension at high-strain rates

The article presents the results of a studies on mechanical behavior of titanium alloy Ti-6Al-4V (Ti Grade 5) in the range of strain rates from 0.1 to 103 s−1. Tensile tests were carried out on flat and notched specimens using the Instron VHS 40/50-20 servo-hydraulic testing machine. High-speed video recording was carried out with a Phantom 711 Camera. The strain fields in the measuring area of the sample were investigated by the Digital Image...
