采用区熔定向凝固方法制备了<110>取向的Tb0.3Dy0.7(Fe1-xAlx)2(x=0,0.05,0.10,0.15)超磁致伸缩合金,在真空管式炉氩气保护条件下,对合金进行930℃×2h的热处理,研究了热处理对于不同含量Al元素替代合金的微观组织、磁致伸缩性能和力学性能的影响.结果表明:热处理不改变Tb0.3Dy0.7(Fe1-xAlx)2合金样品定向凝固形成的<110>轴向择优取向,热处理后的合金棒样品依然保持MgCu2型立方Laves相和部分稀土相结构,没有新相对应的衍射峰产生.热处理后Tb0.3Dy0.7(Fe1-xAlx)2合金的片层组织退化,随着Al元素含量的增加,基体内的析出相形态和分布不断发生变化.当Al的添加量为x=0.05和x=0.15时,热处理后合金的磁致伸缩性能下降,饱和磁致伸缩分别为817×10-6,571 × 10-6.Al的添加量x=0.10时,热处理在不降低合金饱和磁致伸缩的同时可以显著提高其压缩强度及低场动态响应.
