Features of the plastic deformation of titanium alloys in impulse loading

Abstract

1. An increase in the rate of impulse loading of VT1-0 α-titanium strengthens twinning in the {1123} planes but with a lower rate the material deforms both by slip in the (0001) plane and by twinning in the\(\{ 10\overline 1 2\} \) plane (with the formation of prismatic loops and cleaved dislocations). The described transition corresponds to deformation of the α-phase with a reduction in temperature, when the probability of cleavage of dislocations increases. 2. The results of tests of VT30 β-titanium alloy under conditions of impulse loading showed that an increase in the impulse loading rate, the same as for α-titanium, increases the probability of cleavage of dislocations. However, the structure of β-titanium is very sensitive to the presence of alloying elements in the alloy.
