Fe-based Glassy and Nanocrystalline Magnetic Alloys

Since the first synthesis of an amorphous phase in Au-Si system by rapid quenching of melt in 1960, a great large number of amorphous and glassy alloys were prepared up to date. Their alloy systems cover almost all metallic elements in the periodic table and can be classified to ferrous and non-ferrous alloy groups. Considering the present application situation and its future prospect of amorphous and glassy alloys, ferrous metal-based amorphous and glassy alloys are particularly important and attractive and their engineering importance has steadily increased toward the creation of a low-carbon society. Here we introduce the development examples of Fe- and Co-based amorphous and nanocrystalline alloys with unique morphologies such as wire, flaky powder and spherical particle and Fe-C base amorphous steels with new alloy compositions, in conjunction with their applications.
