ATOM PROBE CHARACTERIZATION OF PREPRECIPITATE CLUSTERS AND PRECIPITATES IN Al-Mg-Si(-Cu) ALLOYS
Pre-precipitation clustering and chemical nature of the metastable precipitates in aged Al-Mg-Si(-Cu) alloys have been investigated by atom probe field ion microscopy (APFIM) and transmission electron microscopy (TEM) for better understanding of the two-step aging behavior and the effect of excess Si. After a prolonged natural aging, co-clusters of Mg and Si atoms are observed in addition to se...
متن کاملA charge transfer ionic–embedded atom method potential for the O–Al–Ni–Co–Fe system
Magnetic tunnel junctions (MTJs) require the growth of a thin (∼20 Å) dielectric metal oxide layer, such as Al2O3, on a ferromagnetic metal layer, such as Co, CoFe, or CoNiFe. The atomic assembly mechanisms that combine to form a uniformly thin metal oxide layer on these metal surfaces are not well understood. The application of molecular dynamics simulations to the growth of metal and metal ox...
متن کاملA modified embedded-atom method interatomic potential for the Fe–C system
A modified embedded-atom method (MEAM) interatomic potential for the Fe–C binary system has been developed using previous MEAM potentials of Fe and C. The potential parameters were determined by fitting to experimental information on the dilute heat of solution of carbon, the vacancy–carbon binding energy and its configuration, the location of interstitial carbon atoms and the migration energy ...
متن کاملPhase relations and precipitation in Al–Mg–Si alloys with Cu additions§
Application prospects in automotive industry have led to extensive studies on 6xxx alloys in recent years. These alloys often contain Cu in varying amounts. This leads to the formation of the quaternary Al–Mg–Si–Cu family of alloys that may exist either as a 6xxx or a 2xxx alloy. These alloys have distinctive properties in part due to the occurrence of a phase, designated as Q, which is stable ...
