| Abstract Scope |
Progress and challenges in understanding the role of process variability during validation of an ICME workflow for sub-solvus nickel superalloys are presented and discussed. A method is developed that considers the cumulative effect of process variability on property predictions by addressing the interaction of primary processing steps with downstream processing steps. Within this approach, microstructural features such as gamma prime attributes are treated as distribution-based quantities that reflect the local chemistry and time-at-temperature process variation. These features are then used in a detailed simulation of a final quench and age heat treatment aimed at predicting the last stages of microstructural evolution and corresponding property outcomes. The process parameters of the workflow are adjusted systematically, and a surrogate model is developed to provide a set of distribution-based property predictions. The relationship between process variation and the predicted property variation is also discussed. |
