Abstract:Experiments and simulations both have verified the presence of 100 dislocations in irradiated W. It is essential to know the properties and behavior of these defects to study the evolution of microstructures at higher scales. We study the thermal stability and transition mechanism of various 100 dislocations formed in a molecular dynamics (MD) database of 230 collision cascades using three different interatomic potentials. The energy of transition of 100 dislocations to more stable 111 dislocations is calculat… Show more
