Popis:	In this study, we report results of an investigation into the failure of Ni60Nb15Ti15Zr10 amorphous alloys occurring during hydrogen permeation performed at 473 K and 573 K. However, the amorphous membrane did not fail during test performed at higher temperatures (673 K and 773 K). The failure of the Pd-coated Ni60Nb15Ti15Zr10 amorphous ribbon is attributed to the cracking of the hydrogenated Pd coating induced by the formation of α′ hydride phase in the low temperature range. 0
