Abstract

The deformation behavior of commercially pure submicrocrystalline and coarse-grained titanium was studied at the macroscopic level. Stress-strain curves of the materials were analyzed. Time-space distributions of local strains were studied at all stages of strain hardening using speckle interferometry. The life time of test specimens of the materials and the coordinates of the fracture region were calculated theoretically and confirmed experimentally. The motion of the zones of localized plasticity was studied. The prefracture stage was shown to involve "condensation" of the zones of localized plasticity and migration of deformation to the fracture neck.
