Microstructure-Property-Design Relationships in the Simulation Era: An Introduction (PREPRINT)
Abstract
Computational methods are affecting a paradigm change for using microstructure-property relationships within materials and structures engineering. This chapter examines the emergent use of quantitative computational tools for microstructure-property-design relationships, primarily for structural alloys. Three major phases are described as a historical 'serial paradigm,' current 'integrated computational materials engineering' and, future 'virtual materials systems' emerging from advances in multiscale materials modeling. The latter two phases bring unique demands for integrating microstructure representations, constitutive descriptions, numerical codes and experimental methods. Importantly, these approaches are forcing a fundamental restructuring of materials data for structural engineering wherein data centers on a hierarchy of model parameterizations and validations, rather than the current application-specific design limits. Examining aspects of current research on microstructure-sensitive design tools for single-crystal turbine blades provides an accessible glimpse into future computational tools and their data requirements.
