Thermal behavior and microstructural evolution of additively manufactured Ni-based superalloys via multi-scale simulation

The Ni-based superalloy is one of the important high temperature structural materials used for the modern aero engines and gas turbines. In order to improve the mechanical properties of additively manufactured Ni-based superalloys, deeply understanding of the selective laser melting (SLM) process and controlling its technological parameter are of great significance. In present work, we regulate the process parameters (scanning speed and laser...
