采用熔体快淬工艺制备了成分为Nd9.5Fe84B6.5xPx(x=0、0.1、0.2、0.3和0.4)的快淬磁带,快淬带由硬磁相Nd2Fe14B和软磁相α-Fe组成.结果表明,P含量对合金Nd2Fe14B相晶粒取向和尺寸有显著影响.当P含量较低时,快淬带两个表面中Nd2Fe14B相晶粒存在以c轴择优取向的(00l)织构,且自由面的织构强度大于贴辊面；随着P含量的增加,织构强度下降.晶粒尺寸对P含量比较敏感,添加0.1％(原子分数)P时,有细化晶粒的作用,此时两个面中Nd2Fe14B相晶粒均较小；随着P含量的增加,晶粒开始粗化.此外,自由面中Nd2Fe14B相晶粒尺寸均大于贴辊面的,且这种差异随P含量的增加而增大.
