ABSTRACT:
The method of the present invention incorporates an amorphous metal powder coated with a ductile crystalline metal or alloy. The coated powder is consolidated to form a dense compact of isolated or continuous amorphous metal particles within a continuous ductile metal network. This provides a material in bulk product form exhibiting improved fracture properties including ductility and fracture toughness.
