Overview

Investigation shows pre-deformation impacts mechanical properties in Mg-rich high-Cu alloy, suggesting optimal strain for balance.

Key Points

  • This research aims to determine how pre-deformation affects the microstructure and mechanical properties of a Mg-rich high-Cu alloy.
  • Conducted hardness measurements and tensile tests.
  • Utilized atomic resolution HAADF-STEM for microstructure analysis.
  • Examined varying pre-deformation strains from 0% to 10%.
  • Identified the optimal pre-deformation strain for strength and ductility balance.
  • Hardness and strength increased with pre-deformation strain up to 10%.
  • Tensile elongation reduced despite increased strain hardening capability.
  • Optimal strain of 5% achieved best strength-ductility combination.
  • Cu segregation behavior was altered by pre-deformation, impacting precipitate structure.
