The size of VC was measured by means of the Moire pattern.The misfit between VC and austenite was also accurately calculated. The M_(23)C_6 en-voloped in VC shell was observed in the long-term aged specimens. The coherentrelation between the intragranular M_(23)C_6 twin and austenite as well as its coherentinterface were studied. The effects of the intragranular precipitation and of thegrain boundary phases in the superalloy on its stress rupture of life were alsodiscussed.
