“…In keeping with the research, continues a few practical examples to design engineer materials and devices on an atomic scale as well as to predict the structure of new materials; the flow of current through a nanostructure; their electrical, physical and mechanical properties and the rates of chemical reactions [11][12][13]. Here, we would like to highlight the microstructural arrangement that makes major contributions in the condensed matter to the development of crystalline and electronic structures correlated with wear life, resistance to reactive degradation, novel electronic devices and nonequilibrium entropic alloys [4,15].…”

“…In addition, the aluminum and their alloys possess a good performance, castability, high mechanical strength properties and attractive resistance to electrochemical surface degradation [7][8][9]. Many investigators describe these advantages as primary kind of light alloys since structural design, architectural applications, to combustion engines, until tribological functions [10][11][12][13]. Recently, AlMg alloys have been applied as matrix alloy to composite materials due to their low density and high wettability [14,15].…”

“…Moreover, various averaging procedures suggest that AlMgSi alloys reach up to 90% extruded volume owing to an attractive combination of mechanical and chemical properties and an excellent response to surface finishing operations [27][28][29]. A gradual increase of extruded pieces continued growth by the 6000 series like in automotive, marine and architectural applications [13,21].…”

Physical properties on solidification process deal with the internal atomic arrangement, named generally microstructure. The microstructure characteristic is essential for the properties of metallic materials, including binary, ternary or eutectic alloys. Thus, despite significant progress on microstructural evolution, numerous challenges still exist for revealing the internal structure to act synergistically with matrix alloy chemical components. It is well known that the internal microstructure of an alloy controls and modifies the nature, interaction type and properties of the existing defects and final applications.At this point, necessary understanding of the correlation between equilibrium and nonequilibrium effects, surface energy and chemical potential for the time of the structures formation is probably the key to solidification that can help to predict the complex of microstructures. For the case of multi-phase solidification, AlMgSi alloy involves thousands of atoms, at the atomic scale, that transit to microstructures while the solid-liquid phase transformation occurs. This chapter outlines the role of solidification physics, and the atomic arrangement is believed to have in influencing mechanical hardness properties and degradation resistance.

In this work, surface metal matrix composites (SMMCs) were fabricated on AA6063 base metal through friction stir processing (FSP). In all the samples for surface composites, grooves of 2 mm × 2 mm were made along the centreline of plates and TiB2 powder (~80 nm) was filled and compacted in these grooves. A pinless tool was employed to initially cover and compact the grooves filled with TiB2 particles to prevent it from sputtering during FSP. Tools of different shoulder diameters (16, 18, and 20) mm with anti-clockwise scrolls on the shoulder surface were used for the FSP with constant pin diameter and pin length. The tool rotational speed of 900 min -1 , traversing speed of 40 mm/min and tilt 2°, respectively, kept constant for all the experiments. Macro, optical micro images and micro hardness tests were used to evaluate the particle distribution. Powder agglomeration was observed in the retreating side of samples processed with 16 mm and 18 mm shoulder diameter tools. On the other hand, significant improvement in particle distribution and excellent bonding with the substrate were observed for the sample processed with 20 mm shoulder diameter tool. The findings of this investigation are important and provide knowledge for better tool design and effective tool selection to bring out better distribution in a single pass. Keywords: friction stir processing, aluminium alloy, shoulder diameter, microstructure V tem prispevku avtorji opisujejo izdelavo in raziskavo izdelanega nanokompozita s kovinsko osnovo (angl.: SMMCs; Surface Metal Matrics Composites) na povr{ini aluminijeve zlitine vrste AA6063, izdelanega s pomo~jo vrtilno (rotacijsko) trenjskega procesa (angl.: FSP; Friction Stir Processing). Vsi vzorci povr{inskega kompozita {irine 2 mm in globine 2 mm so bili izdelani vzdol`sredi{~ne linije kovinske plo{~e. Pri tem so bili med FSP dodajani pribli`no 80 nm delci TiB2 prahu v nastajajo~e brazde. Za za~etno prekrivanje in kompaktiranje brazd napolnjenih s TiB2 so uporabili orodje brez trna in s tem prepre~ili razpr{evanje delcev med FSP. Za izdelavo SMMCs so uporabili dr`ala razli~nih premerov (16, 18, in 20) mm z valj~ki, name{~enimi na povr{ini dr`al, ki so se vrteli v nasprotni smeri urnega kazalca. Pri tem so za FSP uporabili trn s konstantnim premerom in dol`ino. Pri vseh preizkusih so za izbrani FSP uporabili hitrost vrtenja 900 min -1 , vzdol`no hitrost potovanja orodja 40 mm/min, in nagib 2°. Da bi ugotovili porazdelitev delcev TiB2 v izdelanih SMMCs so izvedli metalografske preiskave in dolo~ili mikrotrdoto kompozitov. Opazili so aglomeracijo pra{nih delcev na vzorcih izdelanih s 16 mm in 18 mm premerom dr`ala orodja. Po drugi strani pa so dosegli pomembno izbolj{anje porazdelitve pra{nih delcev in njihovo odli~no vezavo s kovinsko osnovo pri vzorcih, ki so bili izdelani z 20 mm premerom dr`ala orodja. Ugotovitve te raziskave omogo~ajo bolj{e oblikovanje in u~inkovito izbiro orodja za doseganje optimalne porazdelitve nanodelcev v kovinski osnovi pri FSP z enim samim prehodom F.

The growing industrial needs for the development of strong load‐bearing materials by powder metallurgy and casting technologies has led to recent progress in the synthesis of in situ hybrid aluminium matrix composites (AMCs). Unlike their conventional counterparts, this class of engineering materials and their physicomechanical properties are sparsely investigated with no satisfactorily systematic approach and are not reviewed up to now. This is why providing an overview summarizing the formation mechanisms of in situ phases and mechanical properties of hybrid AMCs can systematically guide the research path in this field. The present review strives to categorize hybrid AMCs based on their dominant in situ formed reinforcements and draw a comparison between different fabrication methods and used starting materials. Finally, the present challenges and potential solutions are addressed both from scientific and technological aspects.
