Abstract
The critical stress intensity factor of Fe40Ni40B20, Ni80Si10B10 and Ni80Si5B15 metallic glass ribbons was measured at temperatures 4.2 to 300 K. The low-temperature embrittlement for Ni-Si-13 glasses was not investigated. The low-temperature embrittlement of Fe40Ni40B20 glass depends on the structural relaxation and is connected with a change from vein pattern fracture surface morphology through chevron morphology up to cleavage.
