Researching the Properties of Samples Fabricated Using Selective Laser Melting from a High-Temperature Nickel-Based Alloy

A possible application of a metal powder composition made of a high-temperature nickel-based alloy with high heat strength (the material is analogous to Inconel 718) in selective laser melting (SLM, an additive manufacturing technology) was considered. Peculiarities of material formation in the cour...
