Flow softening behavior during dynamic recrystallization in Mg-3Al-1Zn magnesium alloy
Wrought magnesium alloys are increasingly commercially important because of their excellent strength to weight ratio. Here, for the first time, the effect of industrial deformation conditions on flow softening and grain size in Mg-3Al-1Zn magnesium alloy is quantified. Unlike conventional thermomechanical processing the alloy shows greater flow softening at higher values of temperature compensated strain rate. This defines the processing conditions to give a uniform microstructure of fine grains. This information has been fed directly into Siemens-VAI (Mick.Steeper@siemens.com), and is directly affecting how they are developing their control systems for magnesium rolling and microstructure optimisation processes.
