摘要: 實驗研究了熱處理對〈110〉取向多晶Fe₈₃Ga₁₇合金磁致伸縮性能的影響.發現Fe₈₃Ga₁₇經過淬火處理后,飽和磁致伸縮應變明顯增大.在25MPa預壓力作用下,飽和磁致伸縮應變超過了300×10^-6.中子衍射和差熱分析實驗表明,Fe₈₃Ga₁₇合金在爐冷過程中存在相結構變化,結構變化導致合金磁致伸縮應變的改變,淬火處理能夠抑制合金中DO₃相的形成,從而使Fe₈₃Ga₁₇合金的磁致伸縮應變增大.

Abstract: The effect of heat treatment on the magnetostrictive properties of a (110)-oriented polycrystal Fe₈₃Ga₁₇ alloy was investigated. It was found that the saturation magnetostrictive strain of the quenched Fe₈₃Ga₁₇ alloy exceeded 300×10^-6 under a compressive stress of 25 MPa. The results of Neutron diffraction and differential thermal analysis confirmed that slow cooling leads to the change of phase structure which resuits in the change of magnetostrictive strain. The increase in magnetostrictive strain of the Fe₈₃Ga₁₇ alloy treated by quenching is explained as that the long-range DO₃ is suppressed.
