MD assessment of irradiation resistance of FeMnNiCr under successive bombardment
Abstract The irradiation resistance behavior of Co-free high-entropy alloy FeMnNiCr under successive bombardment is investigated by means of molecular dynamics simulations. There are much less residual defects in FeMnNiCr referring to Ni after prolonged irradiation and large-size defect clusters are observed in FCC Ni but not FeMnNiCr. The formation and growth of dislocations in FeMnNiCr are significantly suppressed. The migration barriers of interstitials are similar to these of vacancies in FeMnNiCr, resulting in a higher efficiency of defect recombination. The defects in Co-free FeMnNiCr show similar trends with NiCoCrFeMn and NiCoCrFe during the irradiation process, suggesting its good potential in nuclear structure materials applications.
