Abstract
This overview presents a comprehensive exploration of the research methodsemployed for the precise assessment of volume fraction and the detailedcharacterisation of the size, shape and distribution of γ' phase precipitates withinNi-based superalloys. These advanced materials exhibit exceptional mechanicalproperties due to the presence of γ' precipitates. The accurate quantification ofprecipitate parameters is crucial for understanding material behaviour and forthe optimisation of alloy design. In this overview, a spectrum of techniques,including microscopy (SEM, TEM), diffraction (XRD), spectroscopy (EDS, EELS)and advanced imaging (3D-APT, STEM-HAADF, FIB-SEM) is discussed. Strengths,limitations and potential synergies among these methods are highlighted, offeringresearchers a comprehensive toolbox to advance their investigations of γ' phaseprecipitates in Ni-based superalloys.
