摘要	It is shown that mechanical alloying in the immiscible Fe-Cu system is governed by the atomic shear event and shear-induced diffusion process. We found that an alpha-to-gamma phase transformation, as evidenced by the Nishiyama-Wasserman orientation relationship, occurs by simultaneous shearing process when the grain size reduces to about 20 nm and Cu content reaches 20 at. % in bcc-Fe(rich)Cu grains in the intermediate stage of milling of Fe(50)Cu(50). Further milling promotes the interdiffusion between fcc-Fe(rich)Cu and fcc-FeCu(rich), which is favored because of the similarity of the lattice structures, until a complete fee Fe-Cu solid solution is formed. The results provide significant insight into the understanding of recent experiments showing that chemical mixing of immiscible elements can bd induced by mechanical alloying.
