摘      要：Mechanical alloying is a solid-state powder processing technique that involves repeated cold welding,fracturing,and rewelding of powder particles in a high-energy ball *** developed about 50 years ago to produce oxide-dispersion-strengthened Ni-and Fe-based superalloys for aerospace and high temperature applications,it is now recognized as an important technique to synthesize metastable and advanced materials with a high potential for widespread *** metastable materials produced include supersaturated solid solutions,intermediate phases,quasicrystalline phases,amorphous alloys,and high-entropy ***,nanocrystalline phases have been produced in virtually every alloy *** of the fneness of the powders,their consolidation to full density without any porosity being present is a challenging *** novel methods have been developed to overcome this *** contamination during milling and subsequent consolidation constitutes another issue;this can be resolved,though expensive.A number of applications have been developed for these novel *** review article presents an overview of the process of mechanical alloying,mechanism of grain refnement to nanometer levels,and preparation of materials such as nanocomposites and metallic *** application of mechanical alloying to synthesize some advanced materials such as pure metals and alloys,hydrogen storage materials,and energy materials is *** article concludes with an outlook on future prospects of this technique.
