Phase Equilibria and Solidification of Mg-Rich Al-Mg-Si Alloys

Precipitation Hardening of Al–Si–Mg Alloys

Property Criteria for Automotive Al-Mg-Si Sheet Alloys

In this study, property criteria for automotive Al-Mg-Si sheet alloys are outlined and investigated in the context of commercial alloys AA6016, AA6005A, AA6063 and AA6013. The parameters crucial to predicting forming behavior were determined by tensile tests, bending tests, cross-die tests, hole-expansion tests and forming limit curve analysis in the pre-aged temper after various storage period...

Oxidation Processes and Phase Changes in Metastable Al–Mg Alloys

Oxidation behavior of metastable mechanical alloys in the Al–Mg binary system has been examined in the context of high-energy density materials and combustion applications. Mechanical alloy powders with compositions ranging from Al0.95Mg0.05 to Al0.5Mg0.5, as well as the component metals, were heated at 20 K/min in oxygen. Differential thermal analysis and thermogravimetric analysis showed that...

Phase relations and precipitation in Al–Mg–Si alloys with Cu additions§

Application prospects in automotive industry have led to extensive studies on 6xxx alloys in recent years. These alloys often contain Cu in varying amounts. This leads to the formation of the quaternary Al–Mg–Si–Cu family of alloys that may exist either as a 6xxx or a 2xxx alloy. These alloys have distinctive properties in part due to the occurrence of a phase, designated as Q, which is stable ...

THERMAL ANALYSIS AND KINETICS OF THE PRECIPITATION IN WROUGHT Al-Mg, Al-Mg-ScAND Al-Mg-Sc-Me (Me=Zr, Ti) ALLOYS

Precipitation behaviour of wrought Al-6Mg alloys with ternary scandium and quaternary zirconium and titanium has been studied. Hardness measurements and resistivity studies are employed to assess the precipitation behaviour of scandium doped Al-6Mg alloy without or with quaternary additions of zirconium and titanium. Further, the kinetics of precipitations are studied by differential scanning c...
