During Phase I, we have conducted proof-of-principle experiments to fabricate exchange-coupled isotropic permanent magnets with SmFeN-Fe4N compositions employing shock wave consolidation technique. We have also successfully synthesized nearly 100% Fe16N2 in bulk form. Under this Phase II plan, we propose to optimize and further enhance the isotropic exchange-coupled permanent magnets with higher energy products. We also propose to fabricate anisotropic exchange-coupled permanent magnets employing forging experiments concomitant with shock compaction. We will examine their texture, microstructure and magnetic properties. We will also continue our efforts to optimize the processing techniques to synthesize bulk Fe16N2 to examine if we can obtain a material with magnetic induction greater than 22 kG.
