SPECIFIC FEATURES OF THE STRUCTURE OF TITANIUM - HYDROGEN AND TITANIUM - DEUTERIUM ALLOYS

The methods of optical and transmission electron microscopy (OM and TE M) are used to investigate the morphology and dislocation structure of phases forming in the process of saturation of titanium with hydrogen and deuterium. Due to a wide range of H and D concentrations, the evo lution of the structure was followed, beginning from the formation of individual hydrides (deuterides) to the nearly perfect hydride state, with concomitantly changing of phase dislocation structure. The observ ed differences in the morphology of hydride and deuteride phases in ti tanium are attributed to different diffusion mobility of hydrogen isot opes.
