We are developing an ICME approach for predicting the influence of composition and manufacturing processes on microstructure and mechanical properties for an advanced high pressure die cast aluminum alloy. The microstructural evolution in an Al-Si-Cu-Mg-based die casting alloy (LIFT380) have been simulated and experimentally investigated. Scheil, DICTRA, and PRISMA modules in Thermo-Calc software were used to calculate the microsegregation resulting from the solidification, homogenization during the solution heat treatment, and precipitation during the aging. The output from the previous module are used sequentially as the input for the next module. In conjunction, quantitative microstructural characterization has been performed and used to adjust and validate the simulation model. Results from Thermo-Calc simulation are being coupled with a physics based strengthening model to predict the yield strength. This entire modeling process can be used to accelerate the design and optimization of high pressure die cast aluminum alloy components and processes.
