摘要
用真空电弧炉熔炼了(Sm0.08Dy0.12)Fe2母合金,在不同温度下进行真空退火,退火温度分别为860℃和700℃,退火时间为72h,发现当经过860℃72h退火后,得到较理想的磁致伸缩系数|λ11-λ⊥|=1420×10-6,对此样品进行了物相、结构以及机理的分析讨论.
Alloy (Sm0.88Dy0.12)Fe2 was prepared with electrical arc furnace in vacuum and the samples were annealed at 860℃ and 700℃ respectively. It is discovered that the magnetostriction |λ11-λ⊥|is 1420×10-6 after annealing at 860℃ for 72 hours. with the x-ray diffraction spectra and the photo of electron microprobe, the discussion was made on the basis of the theory of the diffusion.
