Features of Microstructure and Mechanical Characteristics of EP741NP Heat-Resistant Ni-based Alloy Powders Produced with the Use of Electron-Beam Melting
An influence of electron-beam melting of a cast billet on the quality of EP741NP alloy powders and compacted specimens is considered. The microstructure of the samples, the content of gas impurities and non-metallic inclusions, combination of mechanical characteristics and fracture features of the destroyed samples are analyzed.
