MICROSTRUCTURAL INVESTIGATION OF IRRADIATED PRESSURE VESSEL STEEL WELD METAL

Abstract
Field-ion microscopy and atom probe microchemical analysis have been employed to characterize the microstructure and solute redistribution in irradiated weld metal. Neutron irradiation promoted the formation of clusters rich in copper, manganese and nickel. The results of this investigation provide important microstructural information concerning the role of nickel and manganese in irradiation-hardening of pressure vessel steel weld metal.
