Abstract
The electrolytic hydrogen pickup of commercial VT1-0 titanium in recrystallized or submicro-crystalline states leads to the formation of a thin hardened layer, which affects the macromechanical characteristics of the material. After short-term hydrogen pickup, both the strength characteristics and plasticity of the specimens under tension increase simultaneously. This phenomenon is explained by the barrier mesoeffect of the surface hardened layer, which retards the macrolocalization of strain in a loaded specimen and its subsequent fracture. As the time of hydrogen treatment grows, the strength characteristics and plasticity of titanium decrease due to the embrittlement of the surface hydrogenated layer.
