Density analysis based on normalized process diagrams : a comparative review of ferromagnetic alloys produced by laser powder bed fusion
Résumé
This research explores additive manufacturing of magnetic materials via Selective Laser Melting (SLM), integrating insights from prior studies. Emphasizing density variation concerning applied energies, our methodology incorporates normalized process diagrams. This analysis revealing an identification of different density regions in the case of Fe-6.5%wt. Si alloy. These regions show the interplay between process parameters and thermophysical material properties, encompassing lack of fusion, keyhole pores and balling. Further, density variations of Fe-3% wt. Si, Fe-6.7%wt. Si, and Fe-6.9%wt. Si alloys are studied, highlighting the impact of silicon content on final density. The present study contributes to understand dynamic interactions shaping magnetic material density. By optimizing process parameters based on density considerations, microstructure tailoring becomes possible, and, so far, an optimization of the magnetic properties.
