摘要The crystal structure of the deuteride of Ti(0.85)Mo(0.15) alloy Ti(0.85)Mo(0.15)D(1.47) is determined by neutron powder diffraction to be a tetragonally distorted fluorite-type structure similar to that of epsilon-phase in Ti-H system. The D concentration and c/a axial ratio of this phase are significantly lower than that in the Ti-H system. The formation of epsilon-phase in the Ti-Mo-H system supports the hypothesis that the electron density change play a role in the delta-epsilon phase transition. Considerable broadening of the reflections is observed in the diffraction patterns. and attributed to the D concentration inhomogeneity and anisotropic microstrain in the lattice of the deuteride.
