Abstract
The authors present a summary of activities in the development of amorphous metals, the development of amorphous core distribution transformer, and the future potential of amorphous materials and transformers. Amorphous metals possess unique properties. Made by rapid quenching of liquid metal, the metal has atoms arranged in a random fashion, making the material easy to magnetize. Transformers made using amorphous materials for cores exhibit losses that are 60%-70% less than comparable transformers made with silicon iron cores. The application of amorphous alloys in transformer designs is described, highlighting some theoretical points about the material as well as practical information about transformer design
