A Normalized Diagram for Compare Densities in Additive Manufacturing of Iron-Silicon Magnetic Alloys
Résumé
This article explores additive manufacturing of magnetic materials
via Selective Laser Melting (SLM), integrating insights from prior
studies. The principal goal is compare densities for different studies
about magnetics materials (FeSi alloys) using a normalized energy
diagram. This diagram is a convenient tool that help in the
identification of different density regions: incomplete melting, bubble
formation, insufficient power for melting, and finally, optimal
conditions. Further, we examine density variations in Fe-3%Si, Fe6.7%Si, and Fe-6.9%Si alloys, highlighting the impact of silicon
content on final density. This comparative analysis provides insights
into the intricate relationship between process parameters and additive
manufacturing of magnetic materials through SLM. This study
contributes to understanding dynamic interactions shaping magnetic
material density. By optimizing process parameters based on density
considerations, microstructure tailoring becomes possible, influencing
the final magnetics properties (magnetic saturation, coercive field and
so on). Thus, the implications of an optimal control of densities is an
important step for a further studies about rapid prototyping of electric
machines by Additive Manufacturing (AM)M
