- Abstract
Fe77Co2Zr9B10Cu2 alloy prepared by melt-spinning was annealed at different heat treatment conditions. The thermal property, microstructure and magnetic property of alloys were investigated by differential thermal analysis (DTA), X-ray diffraction (XRD), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM). Fe77Co2Zr9B10Cu2 alloy as-quenched is a mixture of α-Fe(Co) phase, H-phase and amorphous phase. With increasing annealing temperature, the H-phase transforms to α-Fe(Co) phase. Coercivity (Hc) of Fe77Co2Zr9B10Cu2 alloy annealed at 600°C for 40 min followed by furnace cooling reaches the minimum value, which is attributed to the small and homogeneous α-Fe(Co) grain structure.
