Abstract

<jats:p>Magnetic materials are becoming increasingly important due to the development of renewable energy sources. Soft magnetic components are used in electric machines such as motors, generators, inverters, converters, transformers, and sensors. In this work, we processed Fe-Si-based soft magnetic materials with powder bed fusion-laser beam (PBF-LB), additive manufacturing (AM) technology. The work considered the development of Fe-Si alloys by powder mixture, additive manufacturing of samples, post-processing heat treatments, and the measurement of magnetic properties. The results showed that the thermal history associated with the processing route leads to a notable change in the magnetic properties of the Fe-Si alloys. It is also seen that the microstructure and therefore magnetic properties of the Fe-Si alloy may be tailored by changing the laser scanning strategy in the PBF-LB process.</jats:p>
