Abstract

Martensitic steels represent the first examples of successful integrated computational materials design and AIM qualification, meeting the technology acceleration goals of the national Materials Genome Initiative (MGI). Parametric design of alloy composition and process specifications employs mechanistic transformation theory in predictive control of martensitic Ms temperatures, precipitation rate constants and critical particle size, as well as solidification microsegregation. Detailed process optimization employs efficient transformation simulators such as the PrecipiCalc code, coupled to heat transfer simulations to accelerate optimization at the component level. Integration of models in Monte Carlo simulation of multistage manufacturing variation enables accurate forecast of minimum property design allowables with calibration by minimal datasets.
