Abstract
Relation between the magnetic characteristics and the microstructure of nitrided iron wire has been studied. The compound and diffusion zones in iron wire are obtained by the nitriding. The compound zone consists of ε(F_(2-3)N), γ`(Fe₄N) and α〃(Fe_8N) nitrides from the surface. But the α〃 translated to γ` when the nitriding time was longer than 60 min. In nitrided iron, saturation magnetization and coercive force are increased from 1714 Gauss to 1740 Gauss and from 75 Oe, to 99 Oe, respectively for 60 min of nitriding time. The measured magnetic characteristics are determined by the mean value of magnetic moments of the constituent phased.
