its mechanical properties, achieving an ultimate compression strength of 1700 MPa and a Young's modulus of 255.28 GPa.According to the DFT results, these improvements are attributed to a balanced interaction between metallic and covalent bonding, producing a highly irradiation-resistant material with an average vacancy formation energy of 2.66 eV.Dislocation analysis conducted via MD revealed that increasing the temperature enhances dislocation mobility, which further improves the ductility of the alloy. ConclusionsIn conclusion, a cost-effective FeCr 2 V-based RMEA with superior mechanical properties, including high strength, ductility, and irradiation resistance, was successfully designed.With properties surpassing HEAs, this alloy demonstrates improved dislocation mobility at elevated temperatures, highlighting its potential for advanced structural applications in extreme environments.
