Abstract

Mechanical and structural properties of Zr₅₀Ni₂₇Ni₁₈Co₅ (at.%) and Ni₅₉Zr₁₆Ti₁₃Nb₇Sn₃Si₂ (at.%) amorphous alloys were studied before and after hydrogenation. In both alloys, upon hydrogenation, a significant reduction in mechanical properties was evident. The occurrence of hydrogen embrittlement was supported by fracture morphology and is further explained based on the corresponding structural changes induced by hydrogenation.
