Thermal behavior and microstructure of Fe_{81 - x}Co_{x}Zr_7Nb_2B_{10} (x = 2, 4, 6) alloys were investigated by differential thermal analysis and X-ray diffraction. Both the supercooled liguid region Δ T_{x} and the first crystallization peak temperature T_{p1} are the lowest and the span Δ T_{p} between T_{p1} and T_{p2} is the highest when 4 at.% Fe is substituted by Co. The crystallization activation energy E_{p1} for Fe_{75}Co_6Zr_7Nb_2B_{10} alloy is the minimum for the heating rates ν = 5-20 K/min. E_{p1} for Fe_{77}Co_4Zr_7Nb_2B_{10} alloy is the minimum for the heating rates ν = 20 - 50 K/min. The crystallization processes of Fe_{81 - x}Co_{x}Zr_7Nb_2B_{10} (x = 2, 4, 6) amorphous alloys are similar on the whole, which is as follows: amorphous → amorphous + α-Fe(Co) → α-Fe(Co) + Fe_3Zr + Fe_2Nb_{0.4}Zr_{0.6}.
