Radiation resistance of refractory high-entropy alloys

Response of refractory high-entropy alloys MoNbTaVW and HfNbTaTiZr to ultrafast radiation is modelled with the hybrid code XTANT-3, combining tight-binding molecular dynamics with the transport Monte Carlo and Boltzmann equation. A two-temperature state with elevated electronic temperature and a cold atomic lattice is studied.
