Most metallic elements have a crystal structure that is either body-centered cubic (bcc), face-
centered close packed, or hexagonal close packed. If the bcc lattice is the …

Mechanical alloying (MA) and mechanical milling (MM) techniques have been widely
utilised over the past two decades for synthesis of various alloys and composites with …
