Abstract
The plastic deformation of an extruded Mg–Al–Mn (AM30) magnesium alloy in the extrusion direction by compression can be characterized by three distinct stages. Twinning was observed in stage A with a decreasing strain-hardening rate. Detwinning occurred due to strong twin–dislocation interactions in stage B, which was represented by an increasing strain-hardening rate over an extended strain range. Stage C with a decreasing strain-hardening rate was due to a reducing resistance of fewer twins to the dislocation slip.
