The core losses of amorphous alloys are much lower than those of silicon steel, and thus the use of amorphous alloys as the core material for distribution transformers has contributed significantly to energy savings. For amorphous metals, several methods have been proposed to improve core losses. Oblique directional magnetic field annealing and the introduction of linear crystallized regions are means unique to amorphous metals. These methods however do not exhibit a significant effect on core loss reduction, because of the small fraction of eddy current losses. Domain refining methods such as mechanical scribing also are not effective in a lower frequency range, unlike silicon steel. This article studies the possibility of further improvements in core losses by applying laser scribing, tension, and chemical polishing to thick amorphous ribbon.
