Research progress in numerical simulation on forming process of nickel-based superalloys in additive manufacturing
Additive manufacturing technology has presented unprecedented opportunities for the production of complex components made of nickel-based high-temperature alloys. However,significant competitive pressures persist in both experimental research and practical production,hindering the rapid advancement of additive manufacturing for nickel-based high-temperature alloys. In recent years,simulations at various scales have increasingly been utilized to guide the additive manufacturing and development of nickel-based high-temperature alloys. Specifically,macroscale simulations concentrate on the thermal history,forming control,residual stress distribution,and mechanical behavior during the forming process. Mesoscale simulations primarily address issues such as laser absorption during the forming process,melt flow within the molten pool,melting and solidification,defect formation,and crack prevention and control. Microscale simulations focus on the microstructural evolution of the materials during the manufacturing process. Multi-scale simulations facilitate cross-scale research in the material forming process by integrating various types of models. This article reviewed the advancements in numerical simulations of additive manufacturing processes for nickel-based high-temperature alloys under macroscopic,mesoscopic,microscopic,and multi-scale conditions. It analyzed the strategies and approaches of different simulation methods for addressing issues related to the formation and control of nickel-based high-temperature alloys in additive manufacturing. Finally,the article forecasts how to advance the application of numerical simulations in the development of nickel-based high-temperature alloys through additive manufacturing,and outlines potential directions for future development.
