“…Speed and time of milling, mass of balls and powder, and ball diameter also contributes to final hardness development. In particular, a pronounced decrease in energy transfer from the balls to the powder was found by raising the amount of balls [35].…”

“…It can also be exploited for the formation of alloys by diffusion mechanisms starting from pure metals, and to produce performs by in situ reaction of nano-reinforcements. Therefore, mechanical alloying, which cannot be separated from the opportunity of breaking up of the nano-ceramic clusters, is a value-added option offered by this particular processing route [9,33,35,39,47,51,[70][71][72][73][74][75][76][77][78].…”

Metal matrix composites reinforced by nano-particles are very promising materials, suitable for a large number of applications. These composites consist of a metal matrix filled with nano-particles featuring physical and mechanical properties very different from those of the matrix. The nano-particles can improve the base material in terms of wear resistance, damping properties and mechanical strength. Different kinds of metals, predominantly Al, Mg and Cu, have been employed for the production of composites reinforced by nano-ceramic particles such as carbides, nitrides, oxides as well as carbon nanotubes. The main issue of concern for the synthesis of these materials consists in the low wettability of the reinforcement phase by the molten metal, which does not allow the synthesis by conventional casting methods. Several alternative routes have been presented in literature for the production of nano-composites. This work is aimed at reviewing the most important manufacturing techniques used for the synthesis of bulk metal matrix nanocomposites. Moreover, the strengthening mechanisms responsible for the improvement of mechanical properties of nano-reinforced metal matrix composites have been reviewed and the main potential applications of this new class of materials are envisaged.

“…Одним из способов упроч-нения алюминиевой матрицы является внесение методом механического легирования (МЛ) [1,2] готовых частиц упрочняющей фазы. В последнее время в качестве упрочнителя все чаще использу-ют керамические наночастицы [3][4][5][6][7]. Уменьшение упрочняющих частиц от микрометрового до нано-размерного диапазона приводит к значительному повышению прочностных характеристик [6].…”

Исследовали форму, размер и микротвердость порошков композиционных материалов на основе сплава Al-2Cu-1,6Mn-0,4Zr (мас.%), упроч-ненных частицами наноалмаза в количестве 0-10 об.%, в зависимости от продолжительности механического легирования (МЛ). Максимальное время обработки в шаровой планетарной мельнице составило 15 ч. Показано, что с возрастанием времени МЛ средний размер гранул ком-позиционных материалов, полученных с использованием стружковых матричных частиц размером порядка 1000 мкм, уменьшается вплоть до 30 мкм. В процессе МЛ микротвердость материалов увеличивается до 270-320 HV. Ключевые слова: металломатричный композиционный материал, дисперсное упрочнение, механическое легирование, морфология, микро-твердость, алюминий, наноалмаз.The shape, dimension, and microhardness of Al-2Cu-1,6Mn-0,4Zr (wt. %) based composite material powders hardened by nanodiamond particles in amount of 0-10 vol. % depending on mechanical alloying duration have been investigated. The maximum run time in planetary ball mill is 15 h. Mean pellet size of composite materials obtained with the use of chip matrix particles of 1000 μm in size is shown to decrease up to 30 μm when mechanical alloying time increases. In the course of mechanical alloying the material microhardness rises to 270-320 HV.

“…improved modulus, as well as low density, which are all highly desirable for aerospace and automotive applications [1][2][3][4][5][6][7][8][9][10][11][12][13] . By reducing the sizes of ceramic particles in AMC`s to nanometer range (<100nm), there is a potential for offering higher strength and fracture toughness.…”

“…In the fabrication of AMNCs, one of the challenges is the difficulty of dispersing nanometre sized ceramic particles homogeneously in the aluminium alloy matrix. One way of overcoming this difficulty is to produce AMNC powders with ceramic nanoparticles homogenously dispersed in the Al or Al alloy matrix of each of the powder particles by high energy mechanical milling (HEMM) of mixtures of metallic powders and the ceramic nanopowders 3,6,8,14 .The nanocomposite powders can be subsequently consolidated using severe plastic deformation processes such as powder compact forging and powder compact extrusion to produce near net shaped components or structural members 2,[7][8][9] . This approach has been used by Hesabi et al 11 who synthesised nanostructured Al-5vol.%Al2O3 nanocomposite powder by HEMM, and consolidated the milled nanocomposite powder into bars by powder compact extrusion.…”
