The aim of this work is to examine in detail the processes of failure of two types of MG based on transition metals whose behavior in loading at low temperatures differs in relation to the chemical composition. The measurements were taken on tapes of Fe//4//0Ni//4//0B//2//0, Ni//8//0Si//1//0B//1//0 and Ni//8//0Si//5B//1//5 metallic glasses. The Ni-Si-B metallic glasses retain their ductile properties recorded at room temperature down to the liquid helium temperature. On the other hand, Fe//4//0Ni//4//0-B//2//0 metallic glass shows a tendency to embrittlement which depends, however, strongly, on the extent of structural relaxation. The low-temperature embrittlement of the metallic glasses based on the transition metals is reflected in a change of the failure mechanism from ductile failure in the plane of the maximum shear stresses to ductile failure in the plane of the maximum normal stresses and to cleavage.
