Path-dependent deformation behaviors of Tb_0.3Dy_0.7Fe_1.95 alloy subjected to magnetomechanical loading

Path-dependent deformation behaviors has been studied in detail for <110> oriented polycrystalline alloy Tb_0.3Dy_0.7Fe_1.95 under two types of magnetomechanical loadings: i) axial compressive stress σ_{{double pipe}} and axial magnetic field H_{{double pipe}} and ii) axial compressive stress σ_{{double pipe}} and transversal magnetic field H_⊥. In each magnetomechanical space, different loading and unloading sequences of stress and magnetic field are employed. The path-dependent results are obtained and compared to show different influences of the stress and the magnetic field on the domain distribution, which is also explained well by the domain switch process. Such investigation is beneficial to understanding the domain switch process and can serve to develop constitutive models under magnetomechanical loading.
