| 摘 要： | 本文研究了在不同烧结制度下元素Gd和Y的含量对烧结Nd16Fe78B6永磁材料的磁性能和显微结构的影响。实验中，分别采用Gd、Y等量取代原合金中的部分Nd，实验结果表明，Gd、Y替代Nd含量最佳范围为0～15％（质量）。烧结温度为1120℃回火温度为800℃时（Gd15Nd85）16Fe18B6合金的磁性能最佳。烧结温度为1120℃回火温度为600℃时（Y15Nd85）16Fe78B6合金的磁性能最佳。显微组织研究表明，两种合金样品分别产生新相钆铁钕氧化物相和钇铁钕氧化物相。

| Abstract: | The effect of Gd, Y element content on microstructure and magnetic properties of sintered Nd16 Fe78B6 was studied by different sintering processes. In experiment, using Gd, Y equivalent alloys to replace the original part of Nd, the results show that optimal content of Gd and Y to replace Nd is in the range of 0-15 wt%. When sintering temperature is 1120℃ and tempering temperature is 800℃, （Gd15 Nd85 ）t6 Fe78 I36 has the best magnetic properties. When sintering temperature is 1120℃ and tempering temperature is 600℃, （Y15Nd85 ）16Fe78B6 has the best magnetic properties. Microstructure studies show that two types of alloy samples produce new gadolinium neodymium iron oxide phase and neodymium yttrium iron oxide phase respectively. |
