Overview

Molecular dynamics simulations reveal the effects of alloy composition, temperature, and hydrogen concentration on hydrogen diffusion and deformation in stainless steels, suggesting tailored...

Key Points

  • The aim is to explore how hydrogen diffusion and deformation mechanisms are influenced by alloy composition, temperature, and hydrogen concentration in austenitic stainless steels.
  • Employed molecular dynamics simulations to analyze hydrogen behavior in FeCrNi-based alloys.
  • Conducted Arrhenius analysis to evaluate activation energy for hydrogen migration based on alloy composition.
  • Examined the impact of temperature and hydrogen concentration on phase transformations and dislocation activity.
  • Low Cr and Ni contents (6 wt.%) induce martensitic transformations leading to stress drops.
  • High Cr or Ni levels (24 wt.%) favor dislocation plasticity, reducing martensitic transformations.
  • Elevated temperatures combined with high hydrogen concentrations enhance dislocation-mediated plasticity, promoting material failure.
