The Fe73.5Si13.5B9Cu1Nb3 alloy ribbons fabricated at circumference speed of 14.65 and 43.96 m/s (labeled as C1 and C2) have investigated by XRD, VSM, electrochemical workstation and SEM. The XRD results show that the low cooling rate sample (C1) has a nanocrystalline/amorphous dual-phase structure and the high cooling rate sample (C2) has an amorphous structure. VSM results show that both C1 and C2 alloy have excellent soft magnetic properties, and C1 alloy shows a strong magnetic anisotropy, which induced by both the ordered atomic bonds of nanocrystalline phase and strong interaction between the nanocrystalline phase and amorphous matrix. The electrochemical polarization test results show that the corrosion resistance property of C2 alloy is better than that of C1 alloy，which is attribute to the heterogeneity structure and internal stress in the ribbon surface formed on the spinning process.
