反铁磁Fe1-xMnx(0.30≤x≥0.55)合金的磁致伸缩
, PP. 1235-1237
Keywords: Fe-Mn合金,反铁磁体,磁致伸缩,磁诱导相变
Abstract:
采用真空感应熔炼法,制备Fe1-xMnx(x=0.30,0.35,0.40,0.50,0.55(原子分数))合金,在1000℃保温24h,炉冷至室温.研究了不同结构Fe1-xMnx合金样品的室温磁致伸缩性能.结果表明,x≤0.40时,Fe1-xMnx合金样品为γ＋ε双相结构,并且ε相体积分数随Mn含量增加而减小,磁致伸缩性能较差;x>0.40时,合金样品为单一的γ相,具有良好的磁致伸缩性能.Fe0.50Mn0.50合金样品在1.9T磁场中的磁致伸缩可达8.73×10-4.
