Precipitation strengthening is a highly complex phenomenon on the nanoscale, responsible
for providing strength in Al-Cu, Al-Mg-Cu, Al-Mg-Zn and Al-Mg-Si alloys. Advances in …

In Al–Mg–Si alloys, additions of only a few weight percent of Mg and Si enable formation of
hardening precipitates during heat treatment. The precipitation is complex and is influenced …

The structural and compositional evolution of precipitates in Al-Mg-Si-Cu alloys were
systematically investigated by atomic resolution high-angle annular dark-field scanning …

Abstract Understanding 6xxx AA (Al-Mg-Si alloys) relies heavily on structural analysis at the
atomic level. Because the nanoscale precipitates that form during artificial ageing essentially …

The precipitation behavior and aging response of an Al-4.9 Cu-0.74 Mg-0.51 Si-0.48 Mn-0.1
Cr-0.08 Ti-0.02 Fe (wt.%) alloy was examined in detail after aging at 170° C with different …

Scanning transmission electron microscopy (STEM) coupled with energy-dispersive X-ray
spectroscopy (EDS) is a common technique for chemical mapping in thin samples …

The natural aging (NA) and artificial aging (AA) behavior of Al-Mg-Si-Cu alloys with different
Mg/Si ratios and Cu additions were systematically investigated by means of hardness test …

AlSi9Mg aluminum alloy flywheel housing components were formed via squeeze casting
and T6 heat treatment was applied to the formed components. The influence of solid solution …

The influence of different Cu addition levels on the age hardening and precipitation
behaviors in an Al356 foundry alloy during artificial aging treatment has been systematically …

A combination of high Cu and excess Mg contents has previously shown excellent effects on
suppressing the natural aging (NA) and enhancing the precipitation strengthening response …
