Abstract Scope |
The additive manufacturing of Ni-based superalloys is inherited with various process-induced defects. In this study, an Integrated Computational Materials Engineering (ICME) based horizontal model integration framework is proposed to integrate plasma atomization, melting and solidification, and microstructural models for the additive manufacturing of superalloy components. The key process parameters include nozzle design and chamber conditions for powder production, input power, scan speed, layer thickness for the melting process, heating temperature, holding time, and cooling rate for the heat treatment process. The synthesized alloy powders are used during the Electron Beam Melting process, and the simulation of powder bed melting examines the role of powder characteristics. The thermal history is used to predict the formation and evolution of the resultant microstructure and defects. The integrated modelling framework provides a comprehensive tool for determining the design set points of associated processes to minimize microstructural defects of additively manufactured Ni-based superalloys. |
