  • The diffusivities of hydrogen in as-quenched and annealed metallic glass Fe39Ni39Si8B12Mn2 were measured by volumenometric methode under different temperatures near room temperature. The activation energy of diffusion was calculated from the results obtained. The structural relaxation caused by annealing tends to decrease the frequency's factor DO and the activation energy, The resonant frequencies of the flexural vibration of the samples during the aging were also measared after charging hydrogen. Some closs relation between the resonant frequencies and the hydrogen contents was observed. It shows that the existence of hydrogen in metallic glass tends to decrease the value of roung's modulus and the reduction of which is proportional to the hydrogen content in sample.
