| Abstract Scope |
Additive manufacturing allows for the piece-by-piece fabrication of complex parts without the wastage associated with subtractive manufacturing methods. In addition to tuning material properties via architectural control, a variety of microstructures can be attained through additive manufacturing via different post-processing treatments. Magnetic materials are underexplored in the field of additive manufacturing; relationships between processing conditions, microstructure, and magnetic properties even more so. By modifying a synthesis method devised for the manufacture of metal parts, we have produced micro-architected magnetic metal-carbon composites with bulk dimensions of 3-5 mm in three compositions: iron, iron-nickel, and copper-nickel-iron. We characterized the magnetic properties of the resultant composites and metal samples of identical composition via vibrating sample magnetometry, finding a three-fold increase and two-fold decrease in coercivity in the iron and copper-nickel-iron microcomposite systems respectively, which was explored via transmission electron microscopy and explained by the predominance of ~10 nm crystallites in the iron system. |
