The H permeation in Fe40Ni38B18Mo4 and Fe81B13.5Si3.5C2 amorphous alloys was evaluated using electrochemical permeation measurements. Due to the different alloying elements in these alloys, higher H permeation rate and effective diffusivity, and lower apparent solubility in Fe40Ni38B18Mo4, amorphous alloys were detected. Here, the behavior of H permeation affected by the alloying elements of C, Si and B in Fe-based amorphous alloys was also described.
