Abstract: Highlights: [•] Methods were proposed to clearly reveal microstructure constituents in Inconel-718. [•] In an as-forged Inconel-718 disk microstructure from center to edge was nonuniform. [•] Microstructure nonuniformities persisted after applying the common heat treatment. [•] So, for both conditions variation in hardness from center to edge of disk was seen. [•] The applied heat treatment was not effective in attaining the required hardness. [ABSTRACT FROM AUTHOR]
