Quantified contribution of β″ and β′ precipitates to the strengthening of an aged Al–Mg–Si alloy

It is generally believed that β″ precipitates, rather than β′ precipitates, are the major strengthening precipitates in aged Al–Mg–Si alloys. The reason for this difference is not well understood. To clarify this, two samples of the same Al–Mg–Si alloy but with different aging states were prepared....
