ResumoSurface integrity characteristics of machined Inconel 718 have been measured using experimental techniques, such as FEG-SEM, EBSD, XRD, TEM, nano-indentation and 3D optical microscopy. Nanosized grains typical of severe plastic deformation are characteristic of the machined surface while deformation in the form of plastic slip bands is typical of subsurface layers. Correlations are presented between deformation features on the machined surface, and cutting parameters and tool wear.
