聚合物粘结Terfenol-D复合材料的制造使用不同尺寸的粉末，也在各种生产条件下，在努力生产Terfenol-D块具有良好的磁致伸缩性能，通过优化的许多制造参数。在1.1 kOe下的536 ppm的大磁致伸缩，结合高d（33）（max）（磁致伸缩-施加磁场曲线中的最大斜率）为1.3ppm/Oe（16.3nm/A）的复合材料在以下条件下制备;平均粒径为137.5 μ m，苯酚含量为3.1wt%，压制压力为0.5GPa。磁致伸缩性能的实现。在这项工作中，比以前报道的类似Terfenol-D复合材料的结果好得多。(C)1999 Elsevier Science B. V.保留所有权利。
Polymer-bonded Terfenol-D composites are fabricated using powders with varying sizes and also under various production conditions, in an effort to produce Terfenol-D bulks with good magnetostrictive properties through the optimization of the many fabrication parameters. A large magnetostriction of 536 ppm at 1.1 kOe, combined with a high d(33)(max) (the maximum slope in the magnetostriction-applied magnetic field curve) of 1.3 ppm/Oe (16.3 nm/A) is obtained for the composite fabricated at the following conditions; the average particle size of 137.5 mu m, a phenol content of 3.1 wt%, and a compaction pressure of 0.5 GPa. The magnetostrictive properties achieved. in this work are much better than the previously reported results for similar Terfenol-D composites. (C) 1999 Elsevier Science B.V. All rights reserved.
