Integrated Computational Materials Engineering (ICME) capabilities are needed to reduce the time and cost required to optimize super vacuum die cast (SVDC) aluminum alloy components. To reach this goal, an understanding of how solutes are partitioned during the non-equilibrium SVDC solidification process is required. A description of solute segregation in a new SVDC A380-based alloy (LIFT 380) is obtained using quantitative electron probe micro-analysis (EPMA) mapping. The experimental results are compared to the segregation profile predicted assuming the Scheil solidification model. In addition, electron backscatter diffraction is used to generate a description of the grain size as a function of distance from the casting surface. The experimental descriptions of this SVDC alloy will be used to calibrate and verify ICME tools for predicting local mechanical properties in thin wall high-pressure die cast aluminum components.
