    Abstract

    Microstructural investigations of thermally aged nuclear grade type 316L stainless steel welds were performed by electron microscopy methods. The microstructures of the thermally aged welds were compared to non-aged condition. Characterization of the secondary phases formed during aging performed by analytical transmission electron microscopy (ATEM) methods and to identify the thermal aging temperatures and times at which microstructural changes can be observed.
