Influence of strain rate and temperature on the structure/property behavior of high-purity titanium

PDF Version Also Available for Download.

Description

The effect of strain rate, temperature, grain size, and texture on the substructure and mechanical response of high-purity polycrystalline titanium is presented. The compressive stress-strain response of 20 and 240 {mu}m grain size high-purity Ti was found to depend on both the applied strain rate; 0.001 {le} {epsilon} {le} 7500 s{sup -1}, and the test temperature; 77 {le} T {le} 873 K. The rate of strain hardening in Ti is seen to increase with increasing strain rate. The substructure of high-purity Ti deformed at high-strain-rate or quasi-statically at 77K displayed a higher incidence of deformation twinning than during quasi-static deformation ... continued below
