Effect of equal channel angular pressing on the deformation behaviour of magnesium alloy AZ31 under uniaxial compression

Deformation behaviour of magnesium alloy AZ31 under uniaxial compression was investigated. AZ31 samples produced by squeeze casting, hot rolling and hot rolling with subsequent equal channel angular pressing (ECAP) were tested. It was shown that ECAP processing produces a fine-grained microstructure that gives rise to improved mechanical properties.
