Dynamic compaction of glassy metal powder generally results in denser noncrystalline components than any other consolidation techniques. For example, a density of more than 90 % of the powder material can be achieved by dynamic compaction whereas it is typically about 70-80% for a component obtained by low temperature (below material's crystallization temperature) mechanical pressing. Bulk amorphous materials other than those in thin film, ribbon and wire forms are of considerable interest from technological standpoints. Thus magnetic properties of dynamically compacted glassy metal powder cores are evaluated. These properties include permeability, core loss, exciting power and B-H behavior. The results are compared with those obtained for mechanically compacted powder cores and ribbon cores.
