ABSTRACT
Amorphous metallic alloys are a new class of metallic materials characterised by the unique combination of the magnetic, electrophysical, mechanical and corrosion properties. The amorphisation of the melt is based on cooling at a relatively high rate in order to prevent the occurrence of the crystallisation processes and, consequently, the self-freezing of the disordered configuration of the atoms. It was assumed over a large number of years that it is not possible to transform the metallic melts to the amorphous state by quenching. There are several methods of producing metallic materials with the amorphous structure which can be divided into three large groups: gas phase deposition of metals; the introduction of defects into the metallic crystal; and solidification of liquid metal. The unique nature of the mechanical properties of the amorphous metallic materials is based on the combination of high strength and sufficiently high ductility. The strength of the amorphous alloys also changes in dependence on the spinning conditions.
