ABSTRACT:

The influence of small additions of gallium, tin, zirconium, antimony in the glass- forming ability CoFeNbBSi metal alloys was observed. X-ray diffraction, transmission electron microscopy, differential scanning calorimetry, and measurements of magnetic susceptibility and electrical resistivity in the crystal and liquid states were used . The conclusion about the ability of gallium and zirconium improve the glass-forming ability of alloys, and tin to lower it. It was found that for a quantitative description of the effect of supplements one can use the call-paramagnetic Curie temperature, if it increases the doping,  and glass- forming ability of the alloy.
