Currently, technological progress in many modern industries requires in implementation of new types of technical materials and related development of new manufacturing technologies that bring both enhancement of service properties of final products, as well as their wider implementation into engineering practice, including the associated energy savings. One possibility is also a constant increasing of consumption of non-ferrous metals. Sustainable development of human society is subject to a maximum economy of non-renewable sources of energy and raw materials, especially metallic ones. One of the ways for achieving this goal, in addition to recycling waste alloys based on aluminium, copper and magnesium, is systematic reduction of their consumption by increasing their quality and service life of utility objects and structures made from them. Already for many years, this happens in metallurgical production for example by alloying or by heat treatment. Production of reinforcing steel by cold deformation by twisting or by tension has brought Significant savings in civil engineering. In this way a significant increase of the yield point and its shifting to the ultimate strength was thus achieved at small decrease in ductility. Technical and economic benefits are obvious: metallurgical irreversible consumption of metals and of financial costs related to it were reduced at producers.One of the ways to the more effective use of metallic materials is their processing by forming. At present in this the area the use of the process of multiple severe plastic deformation (SPD process), leading to a refinement of the structure (materials with UFG structure) and thus to achievement of higher level of their utility value, is expanding.Keywords: Metallurgy, steel, properties, applications, testing methods, SPD process
