Unusual softening of the Nb and V lattice due to dissolved hydrogen (deuterium)

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

We report on X-ray Bragg intensity measurements in the high concentration range of NbH x and VD x as a function of temperature andH(D) concentrationx. The mean square thermal displacements of the metal atoms decrease with increasingH(D) concentration. For concentrations higher thanx∼0.7 a sharp increase was observed. The metal lattice first stiffens withH(D) dissolution and then becomes very soft.
