The overall product engineering process is a complicated iterative task that requires many points of interaction between the various components of the design process. Uncertainty quantification (UQ) is one such interaction/design point that is often overlooked or under-appreciated in most computational materials design frameworks. This talk presents the idea of Envelopes of Uncertainty, novel graphical representations of expected output values calculated from systematic variations of input value uncertainties. An easy to read visualization of the model sensitivity and effective design space of the material emerges, enabling effective communication between the various members of the design team. This UQ approach was applied to a computational framework that prescribes heat treatments based on desired size distributions of precipitates. Inputs were separated into two groups i) precipitation model parameters and ii) processing variables, based on their end-use relevance to material scientists and process engineers, respectively.
