| 中文摘要 | Nanostructured Pr(8)Fe(86-x)V(x)B(6-y)C(y) (x = 0, 1; y = 0, 1) ribbons composed of Pr(2)Fe(14)B and alpha-Fe phases with a high coercivity are fabricated by direct melt spinning. The effects of a single addition of V and a combined addition of V and C on the structures and magnetic properties of melt-spun Pr(8)Fe(86)VB(6-x)C(x) (x = 0 and 1) ribbons have been investigated. Compared with addition-free ribbons, 1 at% V addition is found to reduce the grain sizes of the samples and improve their magnetic properties due to a strong exchange coupling between the hard and the soft phase. A remanence ratio of 0.82, a coercive field of 6.2 kOe and a maximum energy product of 23.4 MGOe in melt-spun Pr(8)Fe(85)VB(6) ribbons are obtained at room temperature. The combined addition of V and C is found to lead to the formation of an intermediate phase of VC at grain boundaries, which appears as a pinning barrier during magnetization and results in an increase of the coercivity value to 6.9 kOe for melt-spun Pr(8)Fe(85)VB(5)C ribbons.
