Abstract

The critical stress intensity factor of Fe40Ni40B20, Fe30Cr10Ni40B20, Ni80Si10B10 and Ni80Si5B15 metallic glass ribbons was measured. Stressing by ultrasound, a new method for preparation a sharp crack in a metallic glass, was used. Only shear rupture failures was investigated for all alloys.
