The deformation behaviour of the magnesium alloy AZ31 under uniaxial compression was investigated using specimens produced by squeeze casting, hot rolling and hot rolling with subsequent equal channel angular pressing (ECAP). ECAP was performed up to 4 passes at 200∘C following route BC leading to a homogeneous fine–grained microstructure and improved mechanical properties. Results of compression tests under various testing conditions as well as microstructural investigations are presented and discussed.
