Hydrogen-Induced Damping Peak Temperatures in Bulk Metallic Glasses

Abstract:

Article Preview

Measurements of the H-induced damping peak in Zr-based multi-component metallic glasses, with different tendency to quasicrystal formation, are added to previous reviews of the properties of this damping peak in metallic glasses, and also compared to Ti-Zr-Ni quasicrystals. The results, mainly discussed in terms of a Snoek-type relaxation mechanism for both structure types, indicate a negative correlation between the degree of icosahedral order and the temperature of the damping peak, so that improved damping properties of hydrogen-absorbing bulk metallic glasses can apparently be expected from stronger deviations from icosahedral short-range order.
