ABSTRACT The present article reports on characterization studies performed on amorphized nanostructured
Al 6063 alloy powder synthesized by mechanical alloying (MA). The as-milled powder
was characterized by X-ray diffraction (XRD) for investigating the development of crystallite
nature and determining the different phases of the materials present, scanning electron
microscope (SEM) was used for in depth morphological study and High Resolution-transmission
electron microscope (HR-TEM) was employed to ensure the development of a nano-structured
nature of the Al 6063 matrix. In the present work alloyed powder was milled for 20 h and 40 h at
300 rpm; and 20 h at 700 rpm in a hardened stainless steel medium. Using Williamson-Hall
equation; crystallite size, lattice strain and lattice parameter of Al 6063 nanostructure alloy
powder was estimated with broadening of XRD peaks. XRD results showed that the crystallite
size of Al 6063 alloy powder reached 32 and 53 nm after 20 h at 700 rpm and 40 h at 300 rpm
