Деформационное поведение и локализация пластической деформации на мезои макромасштабном уровнях в субмикрокристаллическом титане

Regular features of plastic deformation development at different scale levels are considered in commercial grade submicrocrystalline titanium in comparison with polycrystalline titanium. It is shown that the former has a high tendency to plastic deformation localization within the range of the thermal stability of its structure (273-573 K). The effects of structural state, temperature, and strain rate on the strain-induced relief development are shown. The character of plastic deformation is found to correspond to the stages of the flow curve of submicrocrystalline titanium.
