英文摘要	the microstructure and texture evolution of mg98.5y1zn0.5 and mg92.5y5zn2.5 (atomic percent) alloys during hot extrusion were systematically investigated. the coarse lpso phases with higher volume fraction (similar to 57%) suppressed the twinning generation in the initial stage of extrusion, and accelerated the dynamic recrystallization through the particle deformation zones. therefore, the volume fraction of drxed grains in as-extruded mg92.5y5zn2.5 alloy was much higher than that of mg98.5y1zn0.5 alloy. the intensive recrystallization process resulted in the conventional basal texture weakening, although the texture evolution was mainly dominated by flow behavior. the dynamic recrystallization behavior in mg92.5y5zn2.5 alloy restricted the formation of deformation texture, and thus the more random texture was observed during the whole extrusion process.
