Additive Manufacturing of Tunable Magnetic Materials for Reversible Patterning
Abstract
In recent years, AM has become a widely-used technology that is changing the way things are manufactured. While researchers have investigated many magnetic materials using additive manufacturing techniques, very few studies have used wire-arc techniques despite the speed and efficient use of material and wide availability of feed wires. In particular, the availability of certain Directed Energy Deposition (DED) additive manufacturing wire-fed approaches (e.g. Sciaky, Wire Arc Additive Manufacturing (WAAM)) can provide build rates of 15-20 lbs./hour. This work will establish a method to process AM magnetic materials using WAAM in an applied magnetic field in order to tune magnetic properties. A custom-built WAAM printer with magnetic field control will be used to develop process windows for magnetic patterning of domain structures. Printing will be conducted on Navy-relevant materials that are either homogenousor heterogeneous in their magnetic phase content and the resulting printed samples will be examined for structure (phases, phase distributions, grain sizes, etc.), mechanical (hardness, tension, etc.), and magnetic properties (coercivity, saturation and remanent magnetization, etc.) to determine success of patterning. The extensive experience and existing collaborations of the PI and coPI in these areas provides an excellent background to ensure rapid progress on these novel AM processing approaches. The project will support a graduate student, partial postdoc, the PI/coPI, and laboratory costs to examine the microstructure, magnetic, and mechanical properties produced via the magnetic field assisted WAAM technique.Approved for Public Release
