Effect of alloying elements on Fe-Si-X soft magnetic material produced by AM and PM

Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsScientificpeer-review


Electrification of the world has significantly increased the demand for novel high performance electromechanical components. Powder Metallurgy (PM) and especially Additive Manufacturing (AM) are seen as enablers to produce components based on novel soft magnetic materials with performance and designs unattainable with conventional manufacturing. Fe-Si-X soft magnetic materials were studied by focusing to tailor material to Laser Powder Bed Fusion (L-PBF) processing. Effect of different alloying elements on magnetic, electrical and mechanical properties were studied based on simulations and experiments. The focus was paid on increasing the understanding of segregation occurring at high cooling rates and how it could be utilized in controlling electrical resistivity and consequently the mitigation of eddy current losses. Gas atomized powder corresponding the most promising alloy composition was produced and further, test components were manufactured by L-PBF accompanied by appropriate heat treatments. The results of resistivity and magnetic measurements are promising when compared against conventional Fe-Si alloy.
