不结盟、排列有 20% 粒子卷部分的结合聚合物的 Tb0.3Dy0.7Fe2 composites 在不同安排域下面被准备(即 0, 10 kA/m, 20 kA/m, 30 kA/m, 60 kA/m 和 100 kA/m ) 在他们的胶化进程期间。静态的磁伸缩,动态磁伸缩,有弹性的模量和所有标本的压缩力量被测试并且比较。试验性的结果显示所有参数确实依赖于安排地。依赖在低地层次是重要的,哪个是为 composites 的 30 kA/m 的批评价值制作了。性质的明显的改进都不能为一块更大的地被观察。如此的批评的值被定义为最佳的安排域生产 magnetostrictive composites。
Non-aligned and aligned polymer-bonded Tb0.3Dy0.7Fe2 composites with 20% particle volume fraction were prepared under different arrangement fields (i.e. 0, 10 kA/m, 20 kA/m, 30 kA/m, 60 kA/m and 100 kA/m) during their gel process. Static magnetostrietion, dynamic magnetostriction, elastic modulus and compressive strength of all specimens were tested and compared. Experimental results indicate that all the parameters are positively dependent on the arrangement field. The dependence is significant at low field levels, the critical value of which is 30 kA/m for the composites fabricated. No obvious improvement of the properties can be observed for a larger field. Such critical values are defined as the optimal arrangement field to manufacture magnetostrictive composites.
