Influence of rare earth element terbium doping on microstructure and magnetostrictive properties of Fe81Al19 alloy
文献摘要：
Fe81Al19Tbx (x =0,0.05,0.1,0.2,0.3,0.4) alloys were prepared by a non-consumable vacuum arc melting technique under an inert argon gas atmosphere.The microstructures of the alloys were studied by X-ray diffraction (XRD) and scanning electron microscopy combined with an energy dispersive spectroscopy(SEM/EDS).The magnetic properties and magnetostriction coefficients of the alloys were measured by a vibrating sample magnetometer (VSM) and adifferential resistive strain sensor,respectively.The results show that the Fe81Al19 alloy consists of a single A2 phase with bcc structure,whereas the Tb doped Fe81Al19 alloys are composed of the A2 phase and a small amount of rare earth-rich phase.The doping of the rare earth element Tb makes the Fe81Al19 alloy preferentially oriented along with the <100> crystal direction.With the increase of Tb content,the magnetostriction coefficient of the alloy first increases and then decreases.When x =0.1,the magnetostriction coefficient reaches the maximum,which is 146 ×106.Compared with the as-cast Fe81Al19 alloy (27 × 10-6),it increases by 441％.The enhanced magnetostrictive properties are mainly attributed to the preferred orientation along <100> of A2 phase of the Tb doped Fe81Al19 alloys and lattice distortion caused by the small amount of rare earth atoms entering the Fe-Al alloy lattice.
