| Abstract Scope |
Fe16N2 has been considered as a potential rare-earth free material with considerable high saturation magnetization, large energy production and high coercivity. One manufacturing process to synthesize bulk quantities of Fe16N2 is nitridation on iron-based alloy with consequent quenching/tempering process. To increase both the nitrogen diffusion and anisotropy energy, introduction of the secondary element has been applied to change the lattice structure of Fe16N2 by replace the nitrogen atom with secondary element atom, or introducing dopants which performs as the pinning sites. The effects of copper on the nitridation and magnetic behaviors of iron-based melt-spun ribbon are studied. The nitrogen diffusion and microstructure after introduction of copper are revealed to show the copper effects. The performance of copper on nitridation efficiency improvement and microstructure which serves better for the anisotropy energy are also discussed for future study and guidance on researching other potential secondary element introduced to iron-based materials. |
