Grain Boundary Controlled Superplasticity of FSP AZ91 Mg Alloy

Key Points

• Superplasticity was observed in the AZ91 magnesium alloy, indicating significant deformation capability under specific conditions.
• Increased deformation rates were achieved, with values exceeding 500%, enhancing applications for lightweight structures.
• Analysis of grain boundaries revealed key mechanisms that facilitate superplastic behavior and improved mechanical properties.
• Further investigation is needed to confirm these findings across different environmental conditions and alloy compositions.
