Recent progress in application of digital/virtual microstructure models in the area of metals engineering science is presented within the paper. First, various approaches to digital reconstruction of microstructure morphology of investigated materials is presented. Possibilities of generation of both: exact replicas of morphology, as well as, synthetic microstructures are discussed. Advantages and limitations in the case of two and three-dimensional problems are highlighted in that section. Then, the state of the art in the evaluation of material properties at the microstructure scale is addressed. Various experimental techniques, characterized by different levels of complexity, which are capable of providing information on materials hardening behavior at the micro scale level are presented. Finally, possibilities of introduction of microstructure morphology with specific properties into the finite element solution are described. The work is complemented by series of practical applications of the digital/virtual microstructure models to show their capabilities and present directions for further development.
