This study presents a design strategy for Al–Mg–Si alloys to control natural aging. Recently,
trace addition of Sn was shown to suppress natural aging for up to two weeks, which was …

The natural aging (NA) phenomena and its negative effect on bake hardening (BH)
response, and a wide temperature/time range of pre-aging (PA) treatment on a novel Al-Mg …

The effects of natural aging (NA) on subsequent artificial aging (AA) at 180° C in Al–Mg–Si–
Cu alloys with varied Mg/Si ratios (0.5, 1 and 2) were systematically studied by Vickers micro …

Many metal alloys are strengthened by controlling precipitation to achieve an optimal peak-
aged condition where the strength-limiting processes of precipitate shearing and Orowan …

Strengthening by needle-shaped β′′ precipitates is critical in Al–Mg–Si alloys. Here, the
strengthening is studied computationally at the peak-aged condition where precipitate …

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 …

Abstract Al–Mg–Si (6xxx series) alloys show excellent mechanical properties due to the
precipitates formed during heat treatment. However, heat treatment of these alloys results in …

Annular dark-field scanning transmission electron microscopy is a powerful tool to study
crystal defects at the atomic scale but historically single slow-scanned frames have been …

The structures of atomic clusters and GP-zones preceding precipitation in an Al-0.70 Mg-
0.85 Si-0.15 Fe-0.25 Mn (wt.%) alloy have been investigated by annular dark field scanning …

This work reports a novel effect of impurity element Cd on enhancing the precipitation
kinetics and increasing the peak hardness of Al–Mg–Si (–Cu) alloys during artificial ageing …
