Directed Energy Deposition Heat-Resistant Nickel Alloy with Vibration Assisted

Abstract:

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.
