Microstructure and mechanical properties of pure magnesium prepared by CEE-AEC at different temperatures

Cyclic expansion extrusion with an asymmetrical cavity (CEE-AEC) was carried out on pure magnesium up to 3 passes at different deformation temperatures of 250 °C and 350 °C. The microstructure texture evolution its edge center regions are studied respectively, their mechanical properties correlated. results show that there is incomplete dynamic recrystallization (DRX) region in deformed Therefore, processing has a larger grain size higher strength than According the tensile test, ultimate (UTS) positions very close because DRXed grains grow But value yield (TYS) nearly doubled, main reasons effect (0001) basal slip softening greater refinement.
