Growth and dissolution behavior and morphology evolution of γ′ precipitates in GH4742 nickel-based superalloy

This work systematically investigated the coarsening, dissolution, and morphological evolution behavior of γ′ precipitates in GH4742 superalloy through carefully designed heat treatment experiments. During long-term aging processes at 650 °C, 750 °C, and 850 °C, the coarsening model of γ′ precipitat...
