Design strategy for controlled natural aging in Al–Mg–Si alloys

“…Age hardenable Al-Mg-Si alloys (6xxx-series) are widely used in the transport, automotive, shipbuilding, and aviation industry [1][2][3]. Aluminum allows lightweight construction for improved fuel efficiency and reduced CO 2 -emissions.…”

“…6xxx-series alloys are especially attractive as they combine good formability with medium to high strength after age hardening, good corrosion resistance, and weldability. In the automotive industry, for example, they are used as outer skin alloys, for non-decorative inner parts, and structural or crash components with individual property criteria [1][2][3][4][5]. Yet, the ever-growing demand to increase formability and strength for more complex parts of lower weight drives the alloy development considerably [4][5][6][7].…”

Clustering in Age‐Hardenable Aluminum Alloys

“…[1] Minimizing energy consumption is the driving force for the application of lightweight materials. Hence one of the main application areas for aluminum alloys is transport.…”

“…Note that here we define clusters to be a homogenous decomposition (local aggregation) of alloying atoms, without a detectable structure or ordering. [1,3] In this review, we focus primarily on two alloy classes where, particularly from the technological point of view, clustering plays the most important role: AlMgSi(Cu) and AlCuMg. [1,[3][4][5] The equilibrium phase common in the AlMgSi(Cu) series is Mg 2 Si (β); with additional small amounts of alloyed Cu the Q phase is also prominent.…”
