| Abstract Scope |
Amorphous metals are exciting because the lack of crystal structure gives them interesting and unique physical, electric, and magnetic properties. One major drawback to these materials is how difficult they are to manufacture. They often require very large temperature gradients that cause fast cooling rates in order to kinetically freeze them. This work demonstrates the ability to electrohydrodynamically print amorphous soft magnetic alloy materials using a reactive ink precursor without rapid cooling. This is possible because they are formed through a chemical reaction rather than a melt. Particle-free Iron – Cobalt reactive inks were made by dissolving organometallic metal carbonyls, such as Iron Pentacarbonyl and Cobalt Octacarbonyl, in organic solvents. These inks can be printed in an inert atmosphere using electrohydrodynamic printing then thermally decomposed into their metallic state using a heated bed at temperatures below 300 °C. |
