Experimental work in labs


The course focuses on the characteristics of properties and processes of preparation of individual types of nano-structural materials: Methods for the synthesis of nano-structural materials (condensation, mechanical milling and alloying, powder metallurgy, spraying of suspensions, electro-deposition, devitrification of amorphous phases, etc.). Moreover individual technological procedures applied in technical practice will also be characterised: Chemical methods for preparation of nano-materials, pulsed laser methods, pyrolysis methods, application of plasma generated by high-frequency. PVD, CVD, epitaxy. New findings from the research of nano-technologies and nano-structural materials focusing on their applications at designing structures. Technology for production of poly-component metallic materials with the basic building units (dimensions, shape, structure, interfacial boundaries) smaller than 100 nm. Special attention is paid to technologies based on severe plastic deformation (SPD) and controlled by conditions of forming. Students will be familiarised with the influence of unconventional forming technologies ECAP (Equal Channel Angular Pressing), High-Pressure Torsion (HPT), CEC (Cyclic Extrusion Compression), TC (Torsion with Compression), Continuous Confined Strip Shearing (C2S2), Continuous DECAP, Conshearing (CS ), Semi-solid Casting (tixoforming) on the structure and mechanical properties of metallic structural micro- and nano-materials. Homogeneity of deformation in ultra-fine grained and nano-structural metallic materials prepared by severe plastic deformation. Determination of stress and strain of individual SPD technologies. Super-plastic behaviour of ultra-fine grained and nano-structural materials. Preparation of nano-structural materials based on Ti and Ti alloys for applications in medicine.
