摘要：

FeB-based alloys were successfully produced by the vacuum arc melting method. FeB-based alloys with various compositions were obtained by the gradual addition of different elements with Cu, Co, and Mo. The structural, magnetic, and electrochemical properties of the produced alloys were investigated. It was de-termined that there was a significant change in the structure with the addition of Mo. It was observed that the Fe3B phase was formed instead of Fe2B depending on the solidification rate. No changes were detected in the phase structure or microstructure, morphology of the other alloys. The hardness changed from 41.88 HRC to 64.24 HRC due to the phase change. All FeB-based alloys demonstrated soft magnetic properties. The lowest coercivity was 13 Oe for the Fe85B15 alloy, and the highest saturation magnetization was 173 emu/g for the Fe63Co21Cu1B15 alloy. While the lowest corrosion resistance was in the Fe85B15 alloy with 6.47 x 10-5 A.cm-2, the highest corrosion resistance was observed in the Fe38Co38Mo8Cu1B15 alloy with 8.21 x 10-6 A.cm- 2.(c) 2023 Elsevier B.V.
