摘要
用电弧炉熔炼法制备了PrxTb0．2Dy0．8-xFe1-85C0.05（x=0．1～0．4）合金。分别采用x射线衍射（XRD）、金相显微镜、振动样品磁强计（VSM）和应变仪分析了合金的结构、金相、居里温度和磁致伸缩。研究发现x≥0．2时，合金中出现了RFe3相和稀土相；居里温度随着Pr含量的增加表现为下降趋势；合金Pr0.2Tb0.2Dy0.6Fe1.85C0.05表现出了较为优良的磁致伸缩特性。
PrxTb0.2Dy0.8-xFe1-85C0.05（x=0.1-0.4） alloys were fabricated by arc-melting method. The structure, metallography, Curie temperature and magnetostriction of alloys were investigated by means of X-ray diffraction, optical microscopy, vibrating sample magnetometer and standard strain technique. RFe3 phase and rare earth phase appear when x≥0.2; Curie temperature decreases with increasing Pr content; Pr0.2Tb0.2Dy0.6Fe1.85C0.05 alloy shows good magnetostrictive properties.
