Purpose: This paper presents the acceptable technology to fabricate epoxy-bonded Tb0.3Dy0.7Fe1.9 composites in an effort to produce Tb0.3Dy0.7Fe1.9 bulks with good magnetostrictive properties through ...
采用粉末烧结法制备了Al/Tb0.3Dy0.7Fe1.95磁致伸缩复合材料,研究了烧结温度对烧结体的显微结构、相组成、磁致伸缩、抗压强度等性能的影响.研究结果表明,600℃烧结时,烧结体中仍主要存在Al与GMM合金相,烧结获得较理想的相分布状态.随着烧结温度的增加,复合体中非GMM相越来越多,原始相减少.当1200℃烧结时,烧结体中主要存在杂相,已几乎没有GMM相.随着烧结温度的增加,复合材料的λ...
