N2 - The effect of shock-induced substructure evolution on the dynamic reloading mechanical behavior of a metastable β titanium alloy, Ti-5Al-2Sn-2Zr-4Mo-4Cr (Ti-17), was systematically investigated in this paper. The preshock treatment with the shock stress amplitude of 6, 10 and 14 GPa were applied on the Ti-17 alloy with equiaxed β microstructure. Then the dynamic reloading tests at strain rate of 3000 s-1 were carried out on these shock-prestrained samples. The results show that, the shock-induced substructure in Ti-17 with equiaxed β microstructure involves shock-induced α"martensite, shock-induced ω phase, dislocation proliferation and slip band. The shock-induced substructure evolution directly influences the mechanical properties of Ti-17 alloy during dynamic reloading.
