ABSTRACT:
Liquid amorphous metal alloy is manufactured into shaped laminations ready for assembly in an inductive component in one process. The rotating chill surface to which the melt is delivered has high thermal conductivity metal in a pattern corresponding to the shaped lamination and is surrounded by thermally insulating material. Melt coming in contact with the high thermal conductivity metal becomes amorphous and that contacting the thermally insulating areas cools more slowly and becomes crystalline. The brittle crystalline scrap is broken away from the strip of laminations and is collected and recycled to the melt.
