Abstract Scope |
Fe-Co alloys, known for their high magnetic saturation and low coercivity, are often used in high performance applications such as electric motors, generators, and transformers. NASA is interested in these alloys for magnetic shielded Hall thrusters. Although these alloys have excellent magnetic properties for these applications, their mechanical properties can make them challenging to fabricate components with complex geometries. Using additive manufacturing (AM), or 3D printing, can aid manufacturability of these alloys, potentially reducing manufacturing cost and lead-time. Additionally, since more than one alloy can be deposited at a time via most directed energy deposition (DED) systems, the fabrication of compositional gradients to stronger, more ductile, and/or weldable engineering alloys is possible. In this talk, advances in DED based AM of Fe-Co based alloys and gradients to improve strength, ductility, and/or weldability will be discussed. |
