Abstract Scope |
FeNiCrMn alloys have attracted considerable attention in High Entropy Alloys (HEAs) research due to their various practical industrial and scientific applications. For a better fundamental understanding, the development of reliable and efficient interatomic potentials for the FeNiCrMn alloy is important. In this work, we constructed an interatomic potential for the
FeNiCrMn system within the embedded atom method formalism to model dislocation movements. The FCC phase of the FeNiCrMn system was stabilized over a wide range of temperatures and compositions. The stacking fault energies and elastic constants are well reproduced for the FeNiCrMn systems in comparison with available theoretical and experimental data. The edge dislocation mobility will be presented in a wide of composition range and temperature range 300-900K. The friction stress increases essentially with the addition of Mn and increasing configurational entropy. |
