Additive Manufacturing of Soft Ferromagnetic Fe 6.5%Si Annular Cores: Process Parameters, Microstructure, and Magnetic Properties

The laser beam melting (LBM) additive manufacturing (AM) technology is used for processing a high silicon steel (Fe 6.5%wtSi). The effects of LBM machine parameters over microstructure and magnetic properties are studied. Particular attention is dedicated to determining the influence of a normalized energy density over the material density, the grain size, and the crystallographic texture and their impact on the magnetic properties: magnetic flux density and coercivity.

Automated summary

This study investigates the effects of LBM machine parameters on the microstructure and magnetic properties of high silicon steel. The influence of normalized energy density on material density, grain size, crystallographic texture, and magnetic properties (magnetic flux density and coercivity) is particularly examined.
