| Abstract Scope |
Our current focus is developing a digital twin for an end-chilled plate casting that can be used for combined computational and physical simulation of casting, solidification, and heat treatment processes in advanced aluminum alloys. The thermal physical properties of the mold materials are calibrated by physically casting and simulating the casting and solidification of pure aluminum in a standard (benchmark) end-chilled plate mold. The reliability of the calibrated digital twin for simulating thermal and solidification parameters in the standard mold is validated with hypo-eutectic aluminum-copper alloys, for which thermal-physical parameters and solidification kinetics are well documented. Then, the validated standard mold and its digital twin are applied to the more complex and not as well documented multicomponent aluminum alloys A356/A357. Measurements on the physical model combined with inverse computations with the digital twin afford expanded thermal physical property and solidification kinetics databases and improved and expanded quantitative quality criteria (predictors). |
