文摘The distinct images of intragranular VC were observed on TEM in superalloy GH36 underwent normal heat treatment and prolonged aging.The size of VC particles were meas- ured by means of Moire pattern,and the misfit between VC and austenite was also calculated. The M23C6 enveloped in VC shell was also observed in the prolonged-aged specimens.The coherent relation between intragranular M_(23)C_6 twins and austenite as well as its coherent in- terface were also studied.
