磁场下Sm0.88Dy0.12Fe2合金的晶格畸变研究
THE STUDY OF LATTICE DISTORTION OF Sm0.88Dy0.12Fe2 ALLOY UNDER LOW MAGNETIC FIELD
【摘要】 本文研究外加磁场情况下,Sm_(0.88)Dy_(0.12)Fe_2合金的微观结构,确定了低磁场(2.5KOe~3.0KOe)下,该合金中(Sm,Dy)Fe_2相由立方晶转变为正方晶系,原子发生了位移,初步分析了微观晶格畸变与宏观磁致伸缩应变的关系。
【Abstract】 This paper investigated the changes of microstructure of Sm0.88Dy0.12Fe2 alloy under externalmagnetic field.The types of lattice distortion in this alloy under low magnetic field (2.5~3.0KOe)were determined by x-ray diffraction,and the relation between lattice distortion and magnetostrictionstrain was analysed.
