| 英文摘要 | Although the stabilizing heat treatment between solution treatment and aging treatment in Inconel 706 alloy is important to improve its stress rupture life, the influence of stabilization heat treatment temperature on the microstructure and stress rupture properties has not been well understood. In this study, heat treatments consisting of three stabilization temperatures (800 degrees C, 845 degrees C, and 880 degrees C) were performed in Inconel 706 alloy. The results showed that the stress rupture properties were improved with the increase of stabilization temperature. When compared with stabilization at 800 degrees C, the alloy stabilized at 880 degrees C exhibited a 96% increase in stress rupture life and a 110% increase in elongation. Furthermore, increasing the stabilization temperature led to the increased amount of eta phase at grain boundaries. The eta phase appeared in granular, rod-shaped or needle-shaped morphology. The microstructure in the grain interior exhibited compact gamma'/gamma" coprecipitates in the samples stabilized at 800 degrees C and 845 degrees C, while that showed noncompact gamma'/gamma" coprecipitates in the sample stabilized at 880 degrees C. The formation of 2.34 vol% eta phase was found to be beneficial for the stress rupture properties. The improvement in stress rupture properties was ascribed to the presence of eta phase and the associated precipitate-free zones at grain boundaries. |
