The role of structure and texture factors in the ductility and deformability improving of magnesium alloys subjected to ECAP

摘要

Equal channel angular pressing (ECAP) in magnesium alloys due to the severe plastic shear deformations provides both grain refinement and the slope of the initial basal texture at 40-50 ° to the pressing direction. Such changes in microstructure and texture contribute to the improvement of low-temperature ductility and deformability of the alloys. On the basis of analysis of data from various researchers, the main structure and texture factors affecting on the ductility increase of the Mg-Al-Zn-Mn alloys were defined.
