Fabrication of nanocrystalline Mg2Si via ball milling process: Structural studies

► Ball milling process has been applied for the development of Mg2Si-based nanostructured material. ► In-situ fabrication of nanocomposite material that consists of nano-Mg2Si and nano-MgO as a minor phase. ► Balls size affects the crystallite size distribution (uni- or bi-modal), measured based on TEM.
