Abstract
Effect of preliminary hydrogenation on formation of the ultrafine-grained structure in titanium alloy of Ti-Al- V-Mo system (VT16 grade) under severe plastic deformation was examined by the methods of transmission electron microscopy and X-ray diffraction analysis. Hydrogenation to 0.15 wt. % is found to decrease the value of plastic deformation (by ∼2 times) and treatment temperature (from 1023 to 923 K) during formation of the ultrafine-grained hierarchically organized internal structure in the VT16 alloy. Formation of the hierarchically organized internal structure in the VT16 alloy is shown to lead to an increase in yield strength, ultimate strength, and resistance to hydrogen embrittlement at room temperature as compared to the coarse-grained state.
