| Abstract: | The element content at grain boundary of advanced Fe\|based superalloy GH871 containing Nb has been studied by Perkin\|Elmer PHI 595 Auger spectrometer. The results indicated that as Pb content in alloy was 5 ppm, the segregation ratio of Pb at grain boundary was about 1200～1700, and as Pb content was 2 ppm the segregation ratio decreased to 500. And the segregation of Ce、P、S、B and C in alloy also existed at grain boundary. |
