Dislocation structures in 16MND5 pressure vessel steel

Bainitic steel 16MND5 is used to manufacture the pressure vessels of pressurized water nuclear reactors. This material undergoes a ductile to brittle transition (DBT) in the fracture mode with decreasing temperature and/or increasing strain rate. In addition, neutron irradiation embrittlement induces an increase of the DBT temperature.
