Abstract
The design techniques of the components on the macro level are established in the scientific community, however are far behind from the real material performance limits. To obtain those limits, the deeper understanding of the material structure is required. The methods of a new comonents production through standard alloying are the basis of the modern material science manufacturing. The design of the materials with expected required performance limits is the next conceptual step for the materials scientist. As results, to make this step, the problem of a precise material structure analyses on the microstructural level is one os the major importance for the next generation materials design. The complexity of the material structure across the scales(macro-micro) requires a new non deterministic methods for better understanding of the connectivity betwen a materials performance and material microstructure features. This work presents a various new research methodologies and techniques of the material microstructure characterization and numerical design with future applications to the anlyses of the material behavior. The focus of the particular research was to analyse a new cross correlation function of the material structure on the micro length scale and develop a novel framework which allows a better understanding of various important material phenomenas such as failure initiation and recrystallization.
