Overview

Review reveals mechanisms of microstructural refinement in Mg-Al alloys, indicating pathways for enhanced strength.

Key Points

  • This review aims to analyze how Mg17Al12 precipitates contribute to the microstructural refinement and strengthening of Mg-Al alloys.
  • Comprehensive review of existing literature on Mg-Al alloys
  • Detailed analysis of thermomechanical treatments and their impact on microstructure
  • Critical evaluation of grain size effects on mechanical properties
  • High sensitivity of yield strength to grain size observed in AZ-series Mg alloys (slope >150 MPa·µm 1/2)
  • Effective grain refinement through severe plastic deformation and controlled heat treatments
  • Optimized strength-ductility synergy proposed for automotive applications through advanced precipitate engineering.
