Property Criteria for Automotive Al-Mg-Si Sheet 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...

Precipitation Hardening of Al–Si–Mg Alloys

Effect of Sn Addition on the Two-Step Aging Behavior in Al-Mg-Si Alloys for Automotive Application

Aluminum alloys of the 6xxx series which contain excess Si or Cu are well used for the automotive applications because of the high age-hardening response. The effect of addition of small amount of Sn on the two-step aging behavior in 1.2%Mg2Si-0.5%Si in excess alloy and 1.2%Mg2Si-0.7%Cu alloy was investigated by means of hardness measurement, differential scanning calorimetry, and transmission ...

The Role of Mg2Si in the Corrosion Behavior of Al-Si-Mg Alloys for Pressureless Infiltration

The role of Mg2Si in the electrochemical behavior of Al-Si-Mg aluminum alloys has been studied using four experimental aluminum alloys with variations in the Si/Mg molar ratio (A1-0.12, A2-0.49, A3-0.89, A4-1.05), in neutral aerated 0.1M NaCl solutions. Accordingly, the corrosion potential in open circuit (Eoc) and polarization resistance (Rp) were measured. Results show that the augment in Si/...

Melt Protection of Mg-Al Based Alloys

This paper reports the current status of Mg melt protection in view to identify near-future challenges, but also opportunities, for Mg melt protection of Mg-Al based alloys. The goal is to design and manufacture sustainable Mg alloys for resource efficiency, recycling and minimising waste. Among alternative cover gas technologies for Mg melt protection other than SF6: commercially available tec...
