THE MEDIUM RANGE STRUCTURE OF HYDROGENATED Cu-Ti AMORPHOUS ALLOYS STUDIED BY ANOMALOUS SMALL-ANGLE SCATTERING OF X-RAYS AND NEUTRON DIFFRACTION

Abstract
Amorphous Cu-Ti alloys, when hydrogenated, reveal a strong small-angle scattered intensity. The anomalous X-ray scattering effect is used to analyse this SAS intensity on both copper and titanium edges. It allows to assert the presence of very small clusters of titanium hydride having the TiH2 composition. These results are in good agreement with those obtained by neutron scattering experiments when using either hydrogen (b < 0) or deuterium (b > 0) for the hydrogenation of the samples
