| Abstract Scope |
Current work in additive manufacturing seeks to apply a wide variety of modeling techniques to the process, structure, properties, and behavior of both additive manufacturing processes and components. However, these models all require accurate input data for the simulated conditions to predict the process and performance of the resulting parts. In processing simulations, modeling the melt behavior requires accurate data on the viscosity and surface tension to predict heat transfer, fluid flow, and their interactions with the developing microstructure. The necessary precision is difficult to achieve using conventional processing techniques due to the high temperature and reactive behavior of molten metals. Containerless processing provides a unique opportunity to measure the surface tension and viscosity of a melt without the influence of an interface between the melt and a container. This technique has been applied to numerous alloys, including Inconel 625. |
