Opis:: Thermal properties, microstructure and magnetic properties of $Fe_{79}Zr_{9}B_{12},$ $Fe_{76}Zr_{9}B_{15},$ $Fe_{39.5}Co_{39.5}Zr_{9}B_{12}$ and $Fe_{38}Co_{38}Zr_{9}B_{15}$ alloys were investigated by differential thermal analysis, X-ray diffraction and vibrating sample magnetometer. High Co addition has a significant impact on the properties of alloys. High Co addition increases the main crystallization peak temperature and the crystallization activation energy. Moreover, high Co addition changes the crystallization products and influences the crystallization processes of $Fe_{79}Zr_{9}B_{12}$ and $Fe_{76}Zr_{9}B_{15}$ alloys. The specific saturation magnetization $(M_{s})$ increases and coercivity $(H_{c})$ decreases by high Co additions.

Opis:: 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) + $Fe_3Zr$ + $Fe_2Nb_{0.4}Zr_{0.6}$.
