The study of mechanical alloying in the Cu–Fe system, as a model system for those with positive heats of mixing, has been investigated. The effects of impact force which pertains to ball-to-powder ratio, rotation speed and milling time, on the strain and grain size of final powders have been studied. The aim of this research was to find the optimum condition for mechanical alloying of Cu–Fe system by the automatic design and analysis of Taguchi experiments. X-ray diffraction (XRD) was used to analyze the effect of incoming energy on the diffusion rate.
