Summary
This subject is focused on characteristic of processes for preparation of individual types of nano-structural metallic materials. Nano-materials are classified and characterised. The subject is oriented also on methods of synthesis of nano-structural materials (condensation, milling, mechanical alloying, spraying of suspensions, electrolystic deposition, de-vitrification of amorphous phases, etc.). New findings from research of nano-technologies are presented with focus on their use in construction. Technologies for production of poly-component materials with basic construction units (dimensions, shape, structure, inter-phase boundary) smaller than 100 nm are analysed.
