Damping method including a face-centered cubic ferromagnetic damping material, and components having same

A method to increase the damping of a substrate, comprising:

• a) creating a face-centered cubic damping material ingot comprising a face-centered cubic damping material, and having a ingot length, ingot width, ingot volume, and ingot thickness, wherein the step of creating the face-centered cubic damping material ingot includes the use of an additive manufacturing process to form at least a first closed internal void within the face-centered cubic damping material ingot, wherein the first void has an initial first void volume, an initial first void length, an initial first void width, and an initial first void height;
• b) rolling the face-centered cubic damping material ingot to create a face-centered cubic damping material foil having a foil grain size, foil length, foil width, foil thickness, and hardness, wherein the rolling process of creating the face-centered cubic damping material foil deforms at least one aspect of the first void producing a final first void volume that is at least 10% less than the initial first void volume, a final first void length, a final first void width, and a final first void height, wherein the final first void length is greater than the initial first void length, the foil thickness is at least 0.25% of the ingot thickness, and a final shape of the first closed internal void has a cross-sectional profile that varies;
• and
• c) applying a portion of the face-centered cubic damping material foil to the substrate.
