Descrição: Fe-20at%Cu alloy powder was prepared by high energy ball milling,and the evolution of phase was investigated by X-ray diffractormeter.The result shows that the Fe(Cu) nanocrystalline supersaturated solid solution is prepared after ball milling for 30 h.The thermodynamics calculation result shows that there is no driving force to form solid solution.The driving force for extension of solid solubility in Fe-Cu immiscible system by high energy ball milling comes from the dynamics.In the subsequent annealing process,the nanocrystalline supersaturated solid solution is decomposed.
