- W2216188510 abstract "摘要 用快淬急冷技术制备了Nd10Fe84-xB6Inx(x=0和1)系列薄带磁体.利用添加和挥发微量In元素的方法从宏观表现上研究了晶粒边界对晶粒之间交换耦合和磁硬化等性能的影响.发现晶粒边界性质以不同方式影响着磁体矫顽力和剩磁比.某些晶界特性，像缺陷、应力等主要影响磁硬化机制；而另外一些性能，如晶界类型、边界处的自旋取向及结晶学相关性等则控制着交换耦合的强度. 关键词: 晶界 / 纳米复合材料 / 热处理 / 微量添加 Abstract The Nd10Fe84-xB6Inx(x=0，1) ribbon magnets were prepared with the melt-spun method. Influences of boundary feature on exchange coupling and hardening were investigated by means of indium addition and evaporation. It was found that hoth coercivity and remanence were affected by the grain boundary but in quite different way. Some boundary features affect hardening remarkably, while others strongly influence the exchange coupling.
