Abstract

Three pure elemental powder mixtures of Zn–22%Al – 18 %Cu, Zn–5 %Al–11 %Cu, and Zn–27%Al –3%Cu (in wt.%) were mechanically alloyed by steel-ball milling processing. The mechanical alloying characteristics were investigated using X-ray diffraction, scanning electron microscopy, and transmission electron microscopy techniques. It was explored that mechanical alloying started with the formation of phases from pure elemental powders, and this was followed by mechanical milling-induced phase transformation. During mechanical alloying, phases stable at the higher temperatures formed at the near room temperature of milling. Nano-structure Zn–Al-based alloys were produced by mechanical alloying.
