| Abstract Scope |
Refractory high entropy alloys (RHEAs) are characterized by their complex multi-element composition, which confer exceptional high-temperature strength retention. This study investigates the radiation-induced defects in the MoNbTaVW alloy, examining both short-term and long-term impacts through molecular dynamics (MD) simulations using LAMMPS. For short-term defect analysis, displacement cascade simulations provide insights into the immediate aftermath of radiation exposure, revealing information about point defects such as vacancies, interstitials, and Frenkel pairs. To understand the long-term implications, the evolution of defects over an extended period is also studied. This comprehensive approach aims to explore the behavior of the MoNbTaVW alloy under varying intensities and durations of radiation exposure. The simulations employ the moment tensor potential (MTP), a machine-learned interatomic potential specifically developed for the MoNbTaVW alloy system. The findings of this study are expected to enhance the understanding of the alloy's performance in radiation-prone environments, supporting its potential application in nuclear technologies. |
