MICROSTRUCTURE, TEXTURE AND MECHANICAL PROPERTIES OF THE MAGNESIUM ALLOY AZ31 PROCESSED BY ECAP

To investigate the influence of equal channel angular pressing on the microstructure and texture of the magnesium alloy AZ31, electron backscattering diffraction and well as neutron diffraction experiments were carried out. Through these experiments it was possible to trace the microstructure and texture evolution with strain accumulated with the increasing number of equal channel angular pressing passes. It was further demonstrated by subsequent compression tests that the microstructural changes produced by equal channel angular pressing have a beneficial effect on both the compressive strength and ductility of AD31.X113634sciescopu
