Outline of Final Research Achievements

In this study we revealed the nano-hetero-structure and its stabilization mechanism as well as glass forming ability with adding P and Cu elements in FeSiB alloy system. A possibility of the synthesis of ribbon, cast-rod and sintered compacts is also investigated. As a result, we could successfully prepare the (Fe76Si10B8P6)100-XCuX (X＝0-0.6) bulk rod-shape sample by a copper mold technique. Powder metallurgical process is also developed for removing the dimensional limitation.
