Abstract: Strengthening method of the nickel-based wrought superalloy and microstructure transformation under different heat treatment processes were summarized. Grain size, inclusion, transformation mechanism of precipitated phase and metallographic evaluation method were concluded. It is expected to provide a reference for optimization of the microstructure and performance and inspection of the nickel-based wrought superalloy.

Key words: Ni-based wrought superalloy, metallographic analysis, microstructure transformation, grain size
