ABSTRACT

Microstructure analysis and synthesis forms an essential part of establishing structure-property relationships of materials. Correlations between the different microstructural features, such as grain boundaries, inclusions and other defects, and the physical behavior of materials can reveal insights into the underlying mechanisms responsible for their observed behavior. For developing high fidelity computational tools, it becomes essential to extract different microstructural characteristics for studying the behavior of materials at different length and time scales. These microstructure characteristics can be utilized to reconstruct virtual microstructures to be used as an input to develop accurate microstructure dependent numerical models. This paper provides a review of different statistical techniques of microstructure analysis and synthesis to determine effective properties of multiphase materials and resolve microstructure dependent fields by explicitly introducing these features from experimental measurements into predictive models. This review provides an understanding of the microstructure correlation functions and the different paradigms such as phase recovery, simulated annealing and Markov random field-based approaches, which use these microstructural descriptors to reconstruct virtual microstructures to model the physical behavior of materials, including their effective structural response. Some areas of future research have been determined based on a critical assessment of different techniques.
