Abstract

Today, porous magnetic materials have been one of the focal points of studies in the field of treatment due to their absorbent properties. This study focuses on the production of porous magnetic FeSi6 alloy using laser powder bed fusion (LPBF) with in-situ alloying. Water atomized Fe and Si powders with high purity were used as the starting materials. Different hatch spacing and exposure time values were investigated to examine their impact on the porosity of the structure. Cylindrical specimens were produced, and their relative densities were measured. SEM analysis and magnetic property measurements were conducted to evaluate the resulting material. The study successfully achieved the production of high-porosity magnetic material, with some control over pore formation through the laser parameters. The magnetic properties of the material demonstrated results consistent with previous studies. Furthermore, the study found that in-situ alloying in the LPBF method yields magnetic properties comparable to those obtained using pre-alloyed powder, indicating the feasibility of this approach.
