Abstract

The effect of reducing the thinning rate when flow forming AZ31B magnesium alloy barrels on the microstructure, crystal orientation, micro-, nano- and macro-mechanical properties was investigated. The results demonstrate that when the magnesium alloy undergoes different degrees of plastic deformation after flow forming, the grain size and dislocation density inside the crystal change greatly, and the evolution pattern of the organization has a significant effect on the mechanical properties of the materials. The stress-strain curve of the cylindrical parts was obtained by nano-indentation and hardness. This is important to improve the mechanical properties of the magnesium alloy.
