Nanostructural materials formation by mechanical alloying: Morphologic analysis based on transmission and scanning electron microscopic observations

摘要: Abstract The development of nanostructured materials offers new scientific and technological perspectives due to the specific interesting physical properties these materials. These derive either from their reduced grain size or structure boundaries, which constitute a significant volume fraction. Mechanical alloying, widely used produce dispersion-strengthened amorphous alloys, has been employed in recent years synthesize nanocrystalline metallic, semiconductors, covalent component-based Based on statistical analysis transmission scanning electron microscopic images, distribution spatial repartition nanostructural material prepared by mechanical alloying and/or attrition are presented for some cases.
