Overview

Randomized trial investigates mechanical properties influenced by solute elements and grain gradient in Fe-Mn alloys, suggesting new material design strategies.

Key Points

  • To analyze how solute atoms and grain gradient affect the mechanical properties of FeMnSiC alloys.
  • Molecular dynamics simulations were employed to model mechanical behavior.
  • The effects of Mn, Si, and C on stress–strain response and dislocation evolution were examined.
  • Microscopic mechanisms like grain boundary migration were assessed.
  • Mn and C improved strength through solid solution strengthening; Si enhanced work hardening but decreased strength and elasticity.
  • GNG design significantly increased Young’s modulus and flow stress while preserving tensile strength.
  • Under GNG, the mechanism facilitated stress transfer and reduced local strain concentration, enhancing work hardening capacity.
