Abstract Scope |
Co-based metal amorphous nanocomposites (MANCs) can be used for various inductor and sensor applications. The as-quenched Co-based amorphous metal ribbons are suitable materials for continuous strain annealing due to their extraordinary mechanical and magnetic properties. During the process of strain annealing, a transverse magnetic anisotropy is induced and is proportional to the applied tension during annealing giving rise to a controllable value of relative permeability. It is this control of magnetic properties which enables the control of temperature rises within the component. We present several tuned permeability profiles for large-scale production of inductor cores for a specified geometry. In addition, analytical models are compared to the experimental hardware examples for further study of localized core losses. By quantifying the magnetic property variations due to strain annealing, we will allow for the incorporation of loss model predictions and integration of optimal strain annealing profiles to achieve final core temperature profiles. |
