High strength and ductility in a novel Ni-based superalloy with γ′ and nanotwins / stacking faults architectures

The variation of microstructure, which depends on the processing history, significantly affects the mechanical properties of alloys. Here, thermo-mechanical treatments were employed to control the microstructure and tune the corresponding mechanical properties of a Ni-based superalloy. The nanotwins...
