چکیده انگلیسی
â¶ The effects of deformation on the microstructure and mechanical properties of ZA62 Mg alloys were studied for the first time. â¶ The ECAP was conducted on the Mg-6Zn-2Al alloy successfully. â¶ The “stripe” structure and a “bimodal” grain size distribution were found. â¶ Superplasticity was achieved in ZA62 alloy processed after two-step ECAP through 10 pass (2 passes at 473Â K and 2-8 passes at 423Â K) and the highest elongation and strain rate sensitivity (m-value) reached 520% and 0.45, respectively.
