Laser-based additive manufacturing processes are increasingly used for fabricating components made of nickel-based superalloys. The microstructure development, and in particular the precipitation of secondary phases, is of great importance for the properties of additively manufactured nickel-based superalloys. This paper summarizes the literature data on the microstructure of Inconel 625 superalloy manufactured using laser-based powder-bed fusion and directed energy deposition processes, with particular emphasis on the phase identification of precipitates. The microstructure of Inconel 625 manufactured by laser-based directed energy deposition in as-built condition is investigated by means of light microscopy and transmission electron microscopy. Phase analysis of precipitates is performed by the combination of selected area electron diffraction and microanalysis of chemical composition. Precipitates present in the interdendritic areas of as-built Inconel 625 are identified as MC and M23C6 carbides as well as the Laves phase.

The paper considers the influence of vibration oscillations on the porosity, structure and properties of compact samples obtained by directed energy deposition. A heat resistant alloy based on nickel Inconel 625 was chosen as the starting material. It was found that oscillations at a frequency of 400 Hz significantly reduce the porosity of samples, and also increase the hardness, due to a finer structure, and minimize the anisotropy of properties depending on the direction.
