Influence of the thermomechanical processing on the superplastic forming of Mg-Al alloys

The aim of this paper is to study the influence of the initial microstructure of several Mg–Al alloys on their superplastic formability and on their post-forming microstructure and mechanical properties. Various thermomechanical processing routes, such as annealing, conventional rolling, severe roll...

It was found that the processing route has only a small effect in the formability of Mg–Al alloys or on the postforming microstructures and properties due to rapid dynamic grain growth taking place at the forming temperatures.
