摘　　要：以Nd2Fe（14）B为基底的稀土永磁材料具有优异的磁性能,其在工业上得到了广泛应用。研究了用稀土Gd部分取代Nd对快淬Nd2.28Fe13.58B1.14薄带磁性能的影响。结果表明：快淬薄带主要由RE2Fe（14）B相组成,同时还有少量的α-Fe相,且磁体的矫顽力随着Gd含量的增加而减小,居里温度（Tc）随着Gd含量的增加而升高,说明Gd元素的添加可提高Nd2Fe（14）B磁体的热稳定性。这些研究将有助于RE2Fe（14）B永磁体的成分设计和制造。The rare-earth（RE）permanent magnets based on Nd2Fe（14）B have excellent magnetic properties,which are widely used in industrial applications.The influences of substitution of Gd for Nd on the magnetic properties of（Nd（1-x）Gdx）（2.28）Fe（13.58）B（1.14）（x=0,0.1,0.2,0.4）melt-spun ribbons were investigated.The results show that the melt-spun ribbons mainly consist of R2Fe（14）B phase with a small amount ofα-Fe phase.The coercivity of the magnets decreases with the increase in Gd content and the Curie temperature（Tc）elevates with the increase of Gd content,which indicates that the substitution of Gd for Nd improves the thermal stability of Nd2Fe（14）B magnets.These investigations could be beneficial to the composition design and manufacture of Nd2Fe（14）B permanent magnets.
