| Abstract Scope |
Annealing has been a popular method to improve the soft magnetism of metallic glasses (MGs), however, the relaxation caused by annealing usually makes MGs brittle and difficult to process. Here, we shall show that the embrittled Fe-based MG induced by annealing can be reductilized and the coercivity can be further lowered through rejuvenation by the memory effect. The synchronous improvement in the plasticity and soft magnetic properties is attributed to the combination effects of releasing much residual stress, decreasing the magnetic anisotropy and homogenizing the glasses during the rejuvenation process. The current work opens a new perspective to improve the properties of MGs by utilizing the memory effect and holds promising commercial application potential. |
