【摘要】 粘结磁致伸缩合成材料是由Terfenol-D金属粉末与高聚物粘结复合而成的磁致伸缩材料。在粘结制备过程中,工艺的确定和工艺参数的选取对材料的磁致伸缩性能有重要影响;经过对不同条件下所制得样品的磁致伸缩性能的对比,确定出最优的工艺路线和工艺参数。Terfenol-D粉末的粒度在98-280μm的范围内,粘结材料的磁致伸缩性能较好。Terfenol-D粉末退火处理对改善粘结材料磁致伸缩性能有重要作用,750℃的退火温度较合适,环氧树脂粘结剂与Terfenol-D粉末的重量百分比为6:100时,粘结材料有较高的磁致伸缩性能。更多还原

【Abstract】 The bonded magnetostrictive composite is compound with Terfenol-D powder and high polymer. In the preparation process, the material’s magnetostriction is importantly dependent on the making certain technics and selecting the parameters of the technics. Through the contrast of sample’s magnetostrictions obtained in the different conditions, we have confirmed the best technics and their parameters, which is very important to the future scientific research and manufacture .更多还原
