Method for optimizing mechanical strength of a casting using microstructure predictions |
摘要 |
A method for quantitatively predicting and consequently minimizing the amount of critical phases such as eutectic Al2Cu formed during solidification of Al-Si-Cu alloys used in a vehicle engine component comprises developing a micromodel to simulate microstructure evolution in cast Al-Si or Al-Cu alloys. The micromodel is calibrated using experimental thermal analysis cooling curves and an optimization process. Microstructure evolution and cooling curves are simulated for a casting using the calibrated micromodel. Precipitation of critical phases such as Al2Cu in the casting is predicted as a function of solidification conditions. The model allows casting process variables to be varied with predictable results so that the casting process can be controlled via the micromodel.
