Abstract

The recrystallization beginning and finishing temperature of superalloy GH909 were studied by X-ray diffraction and optical microscopy.The results show that the recrystallization of superalloy GH909 begins at 915℃ and finishes at 980℃ respectively and from 995℃ up the grain is growing slowly.
