  1. Compositional Partitioning in Metastable Nanocrystalline BCC Phase Using 3D-APFIM Michael McHenry, Carnegie-Mellon University, DMR 0406220 “State-of-the-art morphous and nanocrystalline soft magnetic materials consist of a nanocrystalline ferromagnetic phase embedded within an amorphous intergranular matrix. For (FexCo1-x)Zr7B4Cu1 HiTPerm alloys with a high Co-content, a metastable nanocrystalline bcc phase is observed despite the expectation of an fcc phase according to the binary equilibrium Fe-Co phase diagram. 3-d atom probe has been employed (with H. Hono, NRIM) to show the Fe-enrichment of the metastable bcc nanocrystals which is believed to be intimately related to the tendency for formation of the metastable bcc phase.
