Notes:
The report presents investigations of the microstructure of commercial Alloy 800 after isothermal ageing at 900°C, carried out by optical microscopy and by transmission electron microscopy using replica and thin foil techniques.The high temperature ageing was characterized predominantly by precipitation of carbides on grain and twin boundaries of the austenitic matrix, as well as on dislocations within the grains. The carbides were identified, using electron microscope diffraction and X-ray phase analysis of electrolytic extractions, as (Cr, Fe)23C6, Ti (C, N) and TiC.
