High throughput multiscale computing has been a favored choice to seek novel material solutions in the vast design space of high entropy alloys. Workflows can be established from chemistry to process and structure with the aim to produce desired properties to achieve enhanced material performance. The complexity of High Entropy Alloy (HEA) microstructures, enveloping multiphase structure and a variety of important strengthening mechanisms, requires an effective method to be capable of modeling time and length scales that can describe deformation, strengthening and failure of HEAs in the variety of applications. To address this requirement, crystal plasticity models are formulated describing microstructure level deformation behavior of HEAs. Modeling results demonstrate the complex material behavior of additively manufactured HEAs, such as phase transformations, deformation twinning, and identifying the sources of failure. The important role of crystal plasticity is established and demonstrated in the ICME workflows.
