Abstract

Creep-rupture behavior of a Fe-Ni-base alloy crept under various conditions has been studied using Electron Backscatter Diffraction (EBSD) and Transmission electron microscopy (TEM). The results indicate that grain orientation did not change after the alloy crept at 700. °C/300. MPa and changed greatly crept at 700. °C/200. MPa. The recrystallization texture near rupture-fracture surface was observed after the alloy crept at 750. °C/150. MPa. A better creep performance was found in the samples with the occurrence of grain rotation dependence of the microstructure and the grain store energy.
