Abstract

Structural characterization of Fe, Al + BN powders mechanically milled from Fe, Al and BN powders as raw materials was performed by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The analyses indicated the production of particles measuring approximately 20 nm. After long milling times a well-dispersed nanostructure was obtained. The high resolution TEM (HRTEM) analysis indicated that some intermetallic particles are coated BN particles similar to a core-shell structure.
