| Abstract Scope |
In castings, void defects can have well-rounded shapes or interdendritic shapes. Modeling and simulation of multi-physics need to be considered in the design phases to attain appropriate mechanical properties of cast components. The data on casting defects, including microstructure features, is crucial for evaluating the final performance-related properties of the component.
In this presentation, the required Integrated Computational Materials Engineering (ICME) models for the prediction of interdendritic casting defects, such as microporosity and hot tears, are reviewed. Numerical simulation results for microporosity are presented for A356 and 319 aluminum alloys using ProCASTTM software. It was found that the calculated pressure in the interdendritic liquid was observed drop at the cavitation pressures. We postulated based on experimental evidence that these regions of high-pressure drops can be used as an indicator on the severity of interdendritic microporosity defects. Examples are given for predicting microporosity defects and microstructure distribution for a plate casting/ |
