“…Also methods of severe plastic deformation ('SPD', e.g. [5], [6], [7], and [8]) were applied to very small samples only. Therefore, this work aimed to apply high pressure torsion (HPT) -the most efficient technique among all the severe plastic deformation SPD methods [9] -to obtain large amorphous samples, and to develop a feasible route to produce bulk crack-free samples.…”

“…Одним из основных методов получения нанокристаллических металлических материалов для большинства известных систем является контролируемая кристаллизация металлических стекол. К настоящему времени наноструктура была получена в широкой группе металлических систем, имеется ряд данных о параметрах нанокристаллической структуры, полученной разными методами [1][2][3][4][5][6][7][8][9][10][11][12][13]. Установлено, что кристаллизация аморфных металлических сплавов очень часто начинается с образования метастабильных кристаллических фаз, в некоторых системах может происходить одновременное образование нескольких метастабильных кристаллических фаз [14]), а в ряде случаев кристаллические фазы [15] могут сосуществовать с квазикристаллическими [16][17][18].…”

The effect of the concentration of alloying components on the crystallization of amorphous (Fe_73Si_13B_9)_1 – _ x _– _ y Nb_ x Cu_ y and (Co_70Si_12B_9)_1 – _ x _– _ y Fe_ x Nb_ y alloys has been studied by X-ray diffraction and transmission electron microscopy in a wide composition region. The formation of the bcc structures in both the alloy groups is shown to be substantially dependent on the alloying component concentrations. The bcc phase is found to form in the cobalt-based alloys in the concentration region, where it was not observed before. In the cobalt-based alloys, the bcc phase appears at a niobium concentration higher than 1 at % and the average bcc nanocrystal size varies from 40 nm (at 1 at % Nb) to 14 nm (at 5 at % Nb). In the Fe-based alloys, nanocrystals with the bcc lattice form at the copper concentrations of 0.45–1 at %, and the average nanocrystal size is dependent on the alloy composition and varies in the range 16–24 nm. The causes of the concentration dependence of the formation of nanostructures in these alloys are discussed.

“…Although submicron grained materials can be successfully produced by most SPD processes, NC materials are obtained only by nonhomogeneous deformation processes with large strain gradients [12][13][14][15][16][17][18][19]. The basis of the SPD method is to increase the free energy of the polycrystals and generate much more defects and interfaces (grain boundaries) in various nonequilibrium processes such as high-pressure torsion [6,8,[20][21][22][23], ball milling [24][25][26][27][28][29][30][31][32][33][34][35], sliding wear [36,37], drilling [38][39][40][41][42], shot blasting and annealing [43][44][45][46], ultrasonic shot peening [15,[47][48][49][50][51][52] and air blast shot peening [16,17,…”

RIASSUNTO.Si presenta una breve descrizione del processo di nanocristalizzazione delle superfici per mezzo di deformazioni plastiche severe. In particolare, si concentra l'attenzione sui processi di pallinatura che fino ad oggi si sono dimostrati efficaci per ottenere superfici nano strutturate e se ne descrive lo stato dell'arte. L'influenza del processo utilizzato sul comportamento del materiale in relazione alle differenti proprietà di interesse è, poi, analizzata criticamente. Infine, sulla base delle attuali conoscenze si tracciano e sottolineano alcuni possibili sviluppi di ricerca in questo settore. ABSTRACT.A brief description of surface nanosrystallization process via severe plastic deformation is presented. To come to the point different shot peening methods which have proved to be able to create nanocrystalline layers are demonstrated clarifying the actual state of the art. Then the influence of the process is reviewed on material behavior and a wide range of affected properties are investigated. On this basis some possible addresses for future research in this field are drawn and underlined.
