摘要：

The effects of Cr addition on the thermal stability, soft magnetic properties and corrosion resistance of Fe79.5-xSi9.5B11Crx amorphous alloys were detailed investigated. It was found that Cr addition has multiple effects on improving those properties of FeSiB amorphous alloys. As Cr content increases from 0 to 5 at%, the coercive force decreases from 2.46 to 2.02 A/m, and the corrosion rate of the alloys in 0.1 M NaCl solution also decreases from 1.83 x 10(-1) to 3.91 x 10(-4) mm.year(-1). Besides, the passive region exceeds 1.13 V for the alloy containing 7 at% of Cr.
