Abstract Zirconium alloys were widely used as fuel cladding in nuclear reactors. Stacking fault pyramid (SFP) is an
irradiation-induced defect in zirconium. In this work, the formation process of SFP from a hexagonal vacancy
plate on basal plane is studied by molecular dynamics (MD) simulations. The results show that, during the
SFP formation from a basal vacancy plate, the dislocation is firstly dissociated into two
partial dislocations and . The former one resides on the basal plane, while the latter one
glides on the first-order pyramidal plane. The … More >
