Abstract : The effects of liquid metal and hydrogen environments on fracture of amorphous alloys has been determined by means of tensile, bend, fatigue and delayed failure experiments. Fractographic features in air and in the aggressive environments are similar except for scale. Fracture occurs along shear bands in all environments. The results are in accord with an enhanced shear mechanism of embrittlement. (Author)
