Abstract Amorphous metal fiber has high corrosion resistance and excellent mechanical properties, making it a kind of good material for reinforcing concrete matrix. The effect of heat treatment on the corrosion behaviour of Fe73-Cr6C9Si1P11 amorphous metal fibers in 0.5 mol/L H2SO4 solution was investigated by electrochemical polarization analysis. Differential scanning calorimetry (DSC) was used to measure the thermal properties. The evolution of the crystallization process after heat treatment was identified by X-ray diffraction (XRD). The results show that the ��-Fe, Fe2P and Fe3P crystalline phases individually precipitate in the amorphous matrix with increasing annealing temperature. The as prepared amorphous sample shows high corrosion resistance with a lower passivation current density and a wider passive region. The corrosion resistance dramatically decreases after the annealing temperature is higher than 400 ��.
