Abstract

Radiation-induced precipitation has been examined in an Nb-stabilised austenitic stainless steel (AISI-348) during heavy ion irradiation in situ within a transmission electron microscope (TEM) at 1073 K. Selected-area electron diffraction (SAED), bright- and dark-field TEM were used to investigate the nature of the precipitates within the austenite phase (γ-Fe). The crystal structure of the precipitates was investigated using TEM and matched with reference data for the Cr23C6 phase. The results herein reported indicate that the concurrent formation of inert gas bubbles may accelerate clustering and precipitation kinetics in the austenite phase during irradiation.
