Abstract:
Fabrication of nanostructured alloy powder in the solid state is being increasingly attracting materials scientist’s attentions due to, advantages of the process in comparison with liquid state processes. In the present study the behaviour of copper diffusion in the aluminium structure during the mechanical alloying has been investigated by analysis the X-ray diffraction patterns and applying Scanning Electron Microscopy (SEM). For different milling interval samples ,the influence of the milling time on the size, structure and morphology of the powder were studied precisely. The results showed a noticeable formation of homogenised solid solution of Al(Cu) phase in the nano structured Al-4.5wt% Cu alloy powder. Lattice parameter measurements suggested that all the Cu was in solid solution after 40 h milling.
