Traditional testing methods such tensile testing have been widely used to characterize the mechanical behavior of materials under severe conditions, but these tests struggle in analysing strain and temperature localization and adiabatic heating at high strain rates. We used synchronized full-field measurements to follow the deformation and temperature throughout a titanium specimen tested at high strain rate and temperatures up to 1120 °C to address the above mentioned problems. The method allowed the tensile behavior of titanium and especially the necking of the specimens to be studied until fracture.
