Anotace
We analyzed the interaction of selected solutes with grain boundaries and its effect on material properties, relation of various types of stacking faults and configurations of dislocation cores which determine high-temperature behavior of materials, and mobility of interfaces in martensitic structures determining the course of martensitic phase transformations.
