Atomic-scale understanding of the relationship of the oxygen content in terms of the three-dimensional distribution of the oxygen atoms and Ti-Ti grain boundary (GB) structure and chemistry is to be carried out, for the purpose of finding out novel metallurgical solutions that mitigate the effects of oxygen and facilitate favored Ti-Ti grain boundary formation by control of the distribution of oxygen atoms and possess wrought grade mechanical properties from hydride-dehydride (HDH) Ti sponge powder for commercial applications.
