Structural analysis showed that the amorphous nature of the alloy was retained for low hydrogen concentrations. But beyond a critical concentration, hydrogenation of the glassy alloy played a major role in altering the structural and thermal stability, and mechanical properties. Particularly for relatively high concentrations (> 16 at.%), hydrogen induced nanocrystallization and simultaneous reduction in fracture strength were observed. Hydrogen embrittlement occurred at high concentrations and was attributed to the reduction in cohesion between atoms due to the presence of hydrogen. (c) 2005 Elsevier B.V. All rights reserved.
