Microstructure evolution and mechanical property characterization of a nickel-based superalloy at the mesoscopic scale

Nickel-based superalloys have become the critical materials of micro-parts depending on outstanding mechanical properties. The effects of the grain size and precipitates on the mechanical properties at the mesoscopic scale are difficult to be revealed using conventional macroscopic material constitutive models. In the present study, the microstructure evolution of the γ″ phase and the tensile mechanical properties of a nickel-based superalloy at...
