Pr_(0.3)Tb_xDy_(0.7-x)Fe_(1.9)Ti_(0.1)合金结构和磁致伸缩被引量：2: 2010年; 采用电弧熔炼方法制备了Pr0.3TbxDy0.7-xFe1.9Ti0.1(x=0.18～0.21)合金,对样品进行不同条件退火处理,并测量了其磁性能。结果表明:退火前样品都有杂相,并且第二相很大程度上影响样品磁致伸缩;700℃,6d退火处理没有有效消除杂相,样品磁致伸缩没有明显得到改善;而900℃,3d退火处理有效地消除了样品的杂相,尤其是x=0.21的样品,几乎呈现完美的单一的MgCu2型Laves相,磁化强度和磁致伸缩系数均有所增加,当磁场为900kA/m时该样品磁致伸缩系数达到了1.12×10-3。; 刘晓兵刘何燕孟凡斌卢遵铭徐学文李养贤; 关键词：磁致伸缩磁滞回线

Synthesis of Iron-Based Laves Phase Containing Praseodymium Magnetostrictive Materials: 2007年; The synthesis and magnetostriction of PrxTb1-x.Fe2, PrxTb1-x Fe2BO2 and PrxTb1-x（Fe0.6Co0.4）2 alloys were investigated in this study. The addition of boron or cobalt atom in PrxTb1-xFe2 could effectively prevent the formation of non-cubic phases, and Pr concentration limit was successfully increased from 0.2 to 0.4. X-ray step scanning for the PrxTb1-xFe2BO2 and PrxTb1-x（Fe0.6Co0.4）2 alloys showed that PrFe2 possessed a large spontaneous magnetostriction λ1111.; 刘何燕董斌李松涛孟祥熙高建波曲静萍李养贤; 关键词：MAGNETOSTRICTION SYNTHESIS
