| 摘 要： | 为改善多晶Fe-Ga合金的磁致伸缩性能，在Fe-Ga合金中掺杂稀土Ce、Tb和Dy元素。 研究了Fe83Ga17和Fe83Ga17R0.6 (R=Ce、Tb和Dy)合金的结构和磁致伸缩性能。结果表明，Fe83Ga17合金由单一bcc结构Fe(Ga)固溶体相组成，而掺杂稀土后的Fe83Ga17R0.6合金中除保持bcc结构的Fe(Ga)固溶体相外，还出现了R2Fe17第二相。掺杂稀土后的Fe83Ga17R0.6合金磁致伸缩系数明显大于Fe83Ga17合金。掺杂不同种类的稀土元素对Fe-Ga合金磁致伸缩性能改善的程度不同。在外磁场为557 kA/m时，Fe83Ga17Ce0.6合金的磁致伸缩系数(206×10-6)明显大于Fe83Ga17Tb0.6 (165×10-6)和Fe83Ga17Dy0.6 (161×10-6)合金的磁致伸缩系数。

| Abstract: | In order to improve magnetostrictive properties of the polycrystalline Fe-Ga alloys, the rare earth elements Ce, Tb and Dy were doped into Fe-Ga alloys. The microstructures and magnetostrictions of Fe83Ga17 and Fe83Ga17R0.6 ( R=Ce, Tb and Dy ) alloys were studied. The results indicated that Fe83Ga17 alloy consists of a single Fe(Ga) solid solution phase with bcc structure. However, the Fe83Ga17R0.6 ( R=Ce, Tb and Dy ) alloys are composed of the Fe(Ga) solid solution phase and a small amount of R2Fe17 secondary phase. The magnetostriction coefficients of the Fe83Ga17R0.6 ( R=Ce, Tb and Dy ) alloys are significantly larger than that of the Fe83Ga17 alloy. The improvement degree of magnetostrictive properties of Fe-Ga alloy varies with different rare earth elements doping into the alloy. The magnetostriction coefficient of Fe83Ga17Ce0.6 alloy (206×10-6) is larger than that of the Fe83Ga17Tb0.6 (165×10-6) and Fe83Ga17Dy0.6 (161×10-6) at the magnetic field of 557 kA/m. |
