Abstract Scope Precipitate strengthened alloys are widely used in various applications. 2000 series Al alloys, particularly, are well-suited for structures under rigorous environmental conditions. Therefore, developing accurate processing-structure-property relationships is necessary to the development of these and other newer alloys. In this work, we developed a crystal plasticity framework based on single-crystal micro-pillar experiments to model Al-4wt. %Cu behavior. Microstructural variations of this alloy such as particle size and spacing can significantly influence its macroscopic response. Thus, accurate transmission X-ray microscopy was used to capture and characterize the evolution of the microstructure (θ’ and θ precipitates) at different ageing times. Here, RVEs are directly imported from 3D experimental images and used in crystal plasticity simulations to render a statistically and microstructurally representative model. It will be demonstrated that the model can reasonably reproduce the experimentally measured macroscopic response at different aging times. The validated framework can then be used to further investigate the strengthening mechanisms at microscopic scale.
