Microstructure evolution in GH4742 superalloy by combining hot deformation and heat treatment

The microstructure evolution of GH4742 superalloy under the coupling action of hot deformation and heat treatment was studied by isothermal compression and then solvus heat treatment (SHT), with particular attention focused on the interaction mechanism between γ′ precipitates and dynamic recrystalli...
