The main limitation of high-strength Co-based bulk metallic glasses for their application as structural materials is the large brittleness. Spontaneously emerging cracks in the alloy degrade the magnetic properties. We analyzed the failure characteristics of Co_{43}Fe_{20}Ta_{5.5}B_{31.5} bulk soft magnetic metallic glass deformed in the compression at room temperature and the low strain rate. Under loading the amorphous structure stores high elastic energy. During the failure this energy is released and the alloy breaks into small particles or powder exhibiting a fragmentation mode.
