| Abstract Scope |
Concentrated Mg-Al-Ca(-Zn) sheet alloys have numerous advantages such as excellent flame retardancy, good corrosion resistance, high strength, and more importantly low material cost. However, poor formability at room temperature (RT) has been the main bottleneck for their wider applications. In this talk, we will demonstrate that the high temperature final rolling could be one of the strategies to improve the RT stretch formability of concentrated Mg-Al-Zn-Ca alloys. A Mg-6Al-1Zn-1Ca alloy sheet subjected to 510 °C final rolling shows an index Erichsen value of 7.9 mm, which is significantly higher than that of the same sheet subjected to 450 °C final rolling (4.1 mm). More excitingly, 510 °C final rolled Mg-6Al-1Zn-2Ca alloy sheet exhibits a large I.E. value of 8.0 mm which has never been achieved in 2 wt% Ca-containing Mg alloys. |
