High resolution transmission electron microscopy study on the development of nanostructured precipitates in Al–Cu obtained by mechanical alloying

[Display omitted] ► Development of defect structures and nanoprecipitates after 10 h of mechanical alloying in Al–Cu system. ► Defects act as nucleation sites of the ɛAl 2Cu 3 phase. ► Incoherent and semicoherent precipitates are identified by TEM–HRTEM. ► Moiré patterns are associated to the ɛAl 2C...
