The mechanical properties of technical materials depend on their structure. They are influenced not only by their chemical composition, but particularly by the structural grain size. Significant changes in the mechanical behaviour of materials are related both to surface and volume properties, and not only in the field of mechanical parameters. A wide range of physical and chemical parameters changes as well. Nano‐materials are the materials, the structural grain size of which is in the dimensional area from 10−9 to 10−7 m. Nano‐particles and nanostructures are thus so small that their behaviour is affected by atomic forces, properties of chemical bonding, and quantum phenomena. The wave nature of the very small particles begins to manifest itself. The aim of the authors is to contribute by their paper to the solution of the problems in the field of material engineering. This means to investigate the specifics in the behaviour of technical materials depending on the change in the structural grain size towards the nano‐areas, as well as the design and use of new techniques of mathematical and physical modelling including the operative measurement method.

“…1 This technique had an added advantage of obtaining Fe and Co based wires in their amorphous state with interesting magnetic 2,3 and mechanical properties. [4][5][6][7] The in-water quenching technique involves freezing of the melt into wires whereby amorphous structure is retained. The retention of such amorphous state is subject to the optimum quenching rate that relates to several process parameters such as stability in molten jet, velocity of rotating water reservoir.…”

The investigation addresses the effect of in-water quenching process parameters on the magnetic properties of Fe and Co based amorphous wires. The in-water quenching process parameters such as water drum speed, crucible nozzle orifice diameter, crucible nozzle to water level separation and gas pressure for melt ejection were found to be critically important to obtain continuous and ductile wires. The thinner wires with a diameter of ,124 mm revealed superior soft magnetic properties with coercivities as low as ,5?63 A m 21 (70?8 mOe) which was attributed to their high amorphous nature and consequent isotropy. This was also manifested from their surface morphology as observed by scanning electron microscopy. The Fe 77?5 Si 7?5 B 15 and Co 72?5 Si 12?5 B 15 (at.-%) wires in their as prepared state revealed high fracture strength, above 3000 MPa, and high microhardness ,1200 HV (Vickers pyramid number).
