Opis:: We analyzed the failure characteristics of the bulk metallic glass $Co_{43}Fe_{20}Ta_{5.5}B_{31.5}$ (at.%) deformed by compression and by bending of the ribbons. Under the load the amorphous structure can store high elastic energy. The surface morphology of nanoscale fracture is in accord with the micromechanisms of the failure of the amorphous structure. The fracture surface consists of a smooth mirror cleavage zone and a river pattern zone with nanosized dimples, arranged in lines respecting the periodic corrugation zones, oriented perpendicular to the crack propagation direction. The presence of the failure initiation centers in the ribbon influences the dynamics of crack propagation and also the surface morphology of the fracture.

Opis:: The Finemet type amorphous alloys are well known as high frequency soft magnetic materials. They have good soft magnetic properties which are characterized by low coercive force and high permeability because of the lack of crystalline anisotropy. The structural stability of the amorphous ribbon of Finemet type modified by Mn, Al and Cr prepared by melt-spinning process was studied using differential scanning calorimetry and dynamical mechanical analysis. With increase of the crystalline portion in the sample, the Curie transition is shifted to the higher temperatures. The magnetic relaxation processes at frequencies above 10⁴ Hz were detected by mass magnetic susceptibility measurement.

Opis:: 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.

Opis:: The method of thermogravimetry in external magnetic field was modified using square wave alternate magnetic field for an estimation of the temperature dependence of the magnetization. This method was used for the study of influence of plastic deformation of the amorphous alloy $Fe_{73.5}Nb_{3}Cu_{1}Si_{13.5}B_{9}$ on the structural changes.
