•The Fe70-77Si8-10B10-12Cr2-3C1-3 (Wt.%) alloy was obtained by SLM technic from amorphous feedstock powder for the first time.•This alloy is mainly composed of amorphous matrix and crystalline phases (equiaxed grains).•The SLM alloy shows good soft magnetic characteristics without orientation at directions X and Z.
To investigate the microstructure and magnetic properties, FeSiBCrC bulk soft magnetic alloy was prepared by selective laser melting (SLM) technology using amorphous feedstock powder in this work. The results show that amorphous structures and crystalline phases occur in the alloy. And this alloy is mainly composed of α-Fe(Si), Fe3Si, FeB and Fe2B. It is mainly composed of metastable grains, equiaxed grains and amorphous matrix. This alloy has high microhardness (nearly 900 HV0.1). The SLMed alloy exhibits good soft magnetic properties. The coercivity of the direction X and direction Z is almost the same, which is 78.8 Oe. And it has great saturation magnetization with 162 emu/g in both directions. This work reveals the potential of fabricating bulk Fe-Si based amorphous soft magnetic alloys via SLM. |
