Precipitation Hardening of Al–Si–Mg Alloys

Fluidized Bed Heat Treatment of Cast Al-Si-Cu-Mg Alloys

The effects of fluidized bed heat treatment on the microstructural and mechanical properties of Al-Si-Cu-Mg cast alloys, namely,3 54 and 319, were studied. The heating rate in fluidized beds (FBs) is greater vis-a`-vis conventional electrical resistancef urnaces (CFs). The high heating ratei nF Bs increases the kinetics of metallurgical phenomena such as Si fragmentation and spherodization duri...

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 ...

Temperature Effects on the Tensile Properties of Precipitation-Hardened Al-Mg-Cu-Si Alloys

Because the mechanical performance of precipitation-hardened alloys can be significantly altered with temperature changes, understanding and predicting the effects of temperatures on various mechanical properties for these alloys are important. In the present work, an analytical model has been developed to predict the elastic modulus, the yield stress, the failure stress, and the failure strain...

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...
