Nanocrystalline Materials

摘要

Reliable production processes and low cost raw materials have made VITROPERM~® (Fe73.5Cu1 Nb3Si15.5B7) the most prominent representative of the new nano-cristalline alloys. The characteristic feature of these materials is a two-phase structure in which a fine-crystalline grain with an average diameter of 10 to 20 nm is embedded in an amorphous residual phase.This structure is responsible for the fact that these materials can reach the highest permeabilities and the lowest coercivities.
