摘要：

The microstructure and crystallographic structure characteristics of as cold-rolled strip and foil with different thicknesses of GH3536 alloy after annealing was investigated by optical microscope (OM), scanning electron microscope (SEM), transmission electron microscope (TEM) and X-ray diffractometer (XRD) to get an insight into the recrystallization and grain growth behavior. The results show that the cold rolled strip and foil of GH3536 alloy show a microstructure composed of elongated grains along the rolling directions, and its main phase was γ. The grain growth equations of the strip and foil with thicknesses of 200,100 and 50 μm annealed at 1050~1150℃ for 10~60 min were established respectively, and the relevant activation energies were acquired as follows: Q200 μm=800.34 kJ/mol, Q100 μm=609.50 kJ/mol and Q50 μm=314.79 kJ/mol. The activation energy of the thinner strip and foil was smaller, and the grain growth was more prone to occur. The main factors affecting the grain growth were related to deformation degree and precipitated particles. © 2023 Chinese Journal of Materials Research. All rights reserved.
