Abstract

The molecular dynamics (MD) simulations illustrate that radiation-induced viscous flow results primarily by the creation of point defects, which act as flow defects. It was found that the calculations were in excellent agreement with the experimental results. Thermal spike models of radiation-induced fluidity (RIF) were carefully analyzed by determining the number of atoms in the liquid and were shown to be at most as efficient as point defects, and then in only some cases.
