Abstract: In present work amorphous alloys Co$_{48}$Fe$_{25}$Si$_4$B$_{19}$Nb$_4$–R (R = Nd, Sm, Tb, Yb) were obtained by planar flow casting in the form of ribbons with 3–5 mm wide and 35–45 $\mu$m thickness. It was found that crystallization process goes into two stages and depends on the used rare-earth addition and its content in the alloy by differential thermal analysis method. Glass-forming ability criteria were calculated. It is shown that paramagnetic Curie temperature of alloys in liquid state can be used as their a-priori criterion of glass-forming ability.

Keywords: amorphous alloys, crystallization, glass-forming ability, differential thermal analysis, X-ray diffraction, rare-earth metals.
