摘要：
Molecular dynamics simulations are carried out to understand the role of different conditions affecting the displacement cascade characteristics in the vicinity of a tilt/twist GB. It is shown that while GB affects the survival of point defects, the basic characteristics of this mechanism is same at different temperatures of the crystal and also for both the tilt and twist boundaries studied.
