Abstract. Co-Fe-Ni-M-Si-B (M = Zr, Ti) amorphous alloys were prepared via mechanical alloying and rapid quenching. The influence of the preparation conditions over the alloy’s characteristics was investigated in the light of several techniques, such as X-ray diffraction, scanning electron microscopy, differential scanning calorimetry, magnetization measurements and in-situ high-temperature X-ray diffraction. It was found that the preparation technique has a significant influence on the thermal stability, magnetic characteristics and the crystallisation kinetic of the amorphous phase. Substitution of transition metals (Ti or Zr) for Si is investigated for the amorphous powders and ribbons. The influence of substitution type over the alloy characteristics is presented and discussed in this paper.
