Popis:	A single phase intermetallic compound Ti 3 Al having DO 19 structure (hexagonal) was hydrogenated by cathodic charging. The structure was monitored by X-ray diffraction (XRD) at different charging times. The XRD results were analyzed by Rietveld refinement and it was found that electrolytic charging produces a hexagonal hydride phase having lattice parameters a =5.858±0.002 A, c =4.657±0.002 A, unlike gas charging samples which produces a cubic hydride. Strong orientation of hydride phase in [0 0 2] direction is observed.
