Structure analysis of CoFeBSiNb(Ga) pseudobulk metallic glasses

Rapidly quenched Co–Fe based ferromagnetic amorphous ribbons and pseudobulk metallic glasses are attractive group of materials for structural and functional use. In the present contribution, structure of as-cast and annealed Co–Fe–B–Si–Nb pseudobulk metallic glasses with increased thickness was investigated by X-ray diffraction (XRD) and transmission electron microscopy (TEM). In addition, influence of a small addition of gallium (2 at.%) into base composition on structure of the ribbon was investigated.
