Abstract Scope Computational thermodynamics modeling tools are highly effective for predicting phase fractions and other equilibrium material properties. Non-equilibrium phenomena such as precipitate nucleation/growth are inherently more challenging to model, and existing calibration datasets for these models are comparatively less robust. Thus, accurate prediction of the structure-process-property relationships for some classes of materials (e.g. precipitation-strengthened alloys) must rely on the coordinated use of modeling techniques and judicious experimental validation. In this work, we present modeling and characterization efforts within an Integrated Computational Materials Engineering (ICME) framework aimed at property prediction in austenitic steels precipitation-strengthened by vanadium carbide (VC) particles. Precipitation modeling software was used to predict VC precipitate characteristics as a function of alloy composition and aging conditions, and these predictions were experimentally validated for selected alloy systems and heat treatment schedules. Results of this study will be discussed in the broader context of ICME approaches to rapid design of new materials.
