Abstract Scope |
Functional grading has recently seen renewed interest with the advancement of additive manufacturing. Unfortunately, the integrity of functional gradients in alloys tends to be compromised by the presence of brittle phases. Recently, CALPHAD-based tools have been used to generate isothermal phase diagrams that are in turn utilized to plan gradient paths that avoid these phases. However, existing frameworks rely extensively on the (limited) ability of humans to visualize and navigate high-dimensional spaces. In this talk, we present some recent advancements toward the development of algorithmic approaches to design functionally graded alloys. The framework leverages computational thermodynamic predictions, machine learning, path planning and roadmapping to identify trajectories in composition space that result in controllable property/performance profiles while avoiding the formation of detrimental phases. Concepts on multi-material design leveraging this framework are also presented. |
