采用快淬法制备Fe_（100-x）Al_x（15-x）Al_x（30）合金，其磁致伸缩性能得到了很大的改善。在Fe_（81）Al_（19）样品中获得了高达-700ppm的大磁致伸缩，约为传统Fe-Al合金块体样品的5倍。这归因于熔融-旋涂法产生的Al-Al原子对的高浓度及其在[100]织构薄带面的强烈择优取向。这种显著的各向异性磁致伸缩反映了强织构薄带样品中存在的磁弹性竞争。带状样品的磁致伸缩的成分依赖性已被发现是一致的散装材料。
Magnetostriction of Fe100−xAlx(15⩽x⩽30) al1oys has been largely improved by using melt-spun method. The large magnetostriction up to −700ppm obtained in Fe81Al19 sample is about 5 times as large as that in conventional bulk samples of Fe–Al composition. It has been ascribed to the high concentration of Al–Al atom pairs created by melting-spinning method and their strongly preferential orientation in [100] textured ribbon plane. The remarkable anisotropic magnetostriction reflects the magnetoelastic competition occurring in those strong textured and thin ribbon samples. The composition dependence of the magnetostriction in ribbon samples has been found to be consistent with bulk materials.
