7000 series aluminum alloys have particularly high strength, if compared to other aluminum alloys or even to some high strength steels. Currently, this alloy is considered on the next developments of automotive structures, as an enabler of improved m

The effect of pre-ageing (PA) time and temperature on subsequent natural secondary ageing (NSA) and paint bake (PB) hardening of an AA6014 Al–Mg–Si alloy was systematically investigated, especially when both parameters change. A wide range of PA

During quenching of aluminium alloys from the solutionising temperature vacancies are partially conserved as excess vacancies, partially lost to vacancy sinks, the exact fractions depending on the cooling rate. Positron lifetime measurements in sampl

Preaging PA is an industrial routine that suppresses the deleterious effect of natural aging and enhances the final paint bake hardening of 6XXX aluminum alloys. In view of the different advantages of PA at high and low temperatures, the effects of p

The deleterious effect of natural ageing (NA) on subsequent artificial ageing (AA) of Al-Mg-Si alloys can be markedly reduced by adding small amounts of Sn owing to the strong interaction between Sn atoms and excess vacancies. The retarding effect of

Precipitation hardening involves solutionising, quenching and annealing steps, the latter often at various temperatures. The phenomena observed in Al-Mg-Si alloys are very complicated and partially not well understood. During and after quenching, sol

The influence of quench rate after solution heat treatment on the microstructure in the as-quenched state and subsequent ageing kinetics of alloy AA6014 was investigated by means of transmission electron microscopy, positron annihilation lifetime spe
