Hall effect in Zr-Ni and Zr-Cu metallic glasses doped with hydrogen

Effectiveness of hydrogen microalloying in bulk metallic glass design

“…The improved malleability observed here can be attributed to a hydrogen-induced introduction of local structural heterogeneity, which generates multiplication of shear bands [18] and thus enhanced plasticity. This structural heterogeneity may also be related to changes in bonding, as hydrogenation is known to change the density of states in Zr-based glasses [35], in particular decreasing the amount of d-electrons near the Fermi level [36]. As such, hydrogen microalloying is expected to increase the degree of metallic bonding in Zr-based glasses [37] and thus to improve their ductility.…”
