Thermal properties, microstructure and magnetic properties of Fe79Zr9B12, Fe76Zr9B15, Fe39.5Co39.5Zr9B12 and Fe38Co38Zr9B15 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 Fe79Zr9B12 and Fe76Zr9B15 alloys. The specific saturation magnetization (Ms) increases and coercivity (Hc) decreases by high Co additions.
