This article is devoted to Inconel 718 heat-resistant nickel alloy. Comparison of samples obtained by high-speed direct laser deposition technology of powders from different manufacturers on their structure and properties was carried out. The dependence of the influence of the chemical composition of the powders on the formation of defects in the studied samples was established
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.
