Abstract

Abstract

The microstructure and the microstructural stability after long time aging(4×10⁴ h) and short aging aging were invetigated on GH132 superalloy. The experimental results show that some brittle phases such as a phase and Laves phase are not observed both in long time aging at low temperature and short time aging at high temperature.However, γ' phase re-precipitation, coarsening and growth and η phase precipitation have been seen after short time aging in GH132 superalloy.
