Abstract
The effect of strain rate on hydrogen embrittlement behaviour of amorp hous Ni-6.6Cr-2.6Fe-7.8Si-14.5B (at pct) alloy in 0.1 mol/L H2SO4 solu tion was studied by the methods of slow strain rate test and electroch emical charging. The results show that fracture stress of the alloy de creases with the decrease of strain rate within a certain range. As a tentative explanation, the effect of strain rate on hydrogen embrittle ment fracture stress was attributed to the interaction between hydroge n and the excess volume in amorphous alloys.
