“…One of its main supposed advantages is the conceptual framework, which underlies the atomistic or microscopic theory of matter that conveys of atoms building micro and nanostructures [14]. 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].…”

“…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]. Therefore, the development of AlMg alloys is an important task, and the differences between binary, ternary and quaternary alloy make them an important research topic.…”

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.

“…Many researchers have reported different methods which are available under severe plastic deformation [SPD] for improving the wear resistance properties of the materials. Few typical SPD techniques includes accumulative roll-bonding [9][10][11], multiaxial forging [12,13], high pressure torsion [14,15], repetitive corrugation and straightening [16,17] and equal channel angular pressing [18][19][20].…”

The current study examines the wear performance of deformed AM90 magnesium alloy using pin-ondisc wear test apparatus under varying load of 30 and 40 N with the sliding distance of 2500 m and 5000 m at constant sliding speed of 3 m s −1 . The samples were processed through equal channel angular pressing were subjected to microstructural, wear studies and are characterized by optical and scanning electron microscopy. Vickers microhardness was carried out to evaluate the relation between the wear behavior of homogenized and ECAP processed samples. Increment in number of ECAP passes increased the grain refinement as observed in the microstructure with reduction in grain size from ∼70 μm (homogenized sample) to ∼4 μm (ECAP 4 pass sample). Increase in wear resistance and hardness were observed for processed samples and the worn faces are analyzed by scanning electron microscopy and energy-dispersive x-ray spectrometer. The worn surfaces revealed the occurrence of wear debris, delamination, ploughing in the direction of sliding and the predominant wear mechanism was considered to be the combination of oxidation and abrasive wear.

“…To date, various bonding methods have been used to prepare Mg/Al bimetallic composites, including accumulative roll bonding [4], hot co-extruding [5], diffusion bonding [6], friction stir welding [7], explosive cladding [8], high-pressure torsion [9], and compound casting. Compared with other methods, the compound casting process can produce excellent metallurgical bonding between dissimilar alloys at a low cost and a simple production procedure [10,11].…”

Magnesium/aluminium clad bars were fabricated by compound casting and multi-pass warm caliber rolling. A Ni interlayer prepared using a plasma spraying process was inserted between the parent metals to improve the interfacial characteristics during the casting process, and the effect of caliber rolling on the evolution of the interfacial microstructure and mechanical properties of the Mg/Ni/Al composites was investigated. The results show that the formation of Mg-Al intermetallic phases was impeded effectively by the Ni interlayer and a typical AZ31/Ni/6061 multilayer structure with metallurgical bonding was formed during the compound casting process. In addition, an inhomogeneous strain distribution in the AZ31 and 6061 alloys were characterized during the rolling process. The AZ31 clad layer accommodated a larger proportion of the plastic strain during the initial passes, while the strain in the Mg core layer increased with increasing number of passes. The Ni interlayer fragmented during the rolling process, and transformed into the dispersed particles at the interface. Meanwhile, the fresh AZ31 and 6061 base alloys squeezed out and bonded together under the rolling force, and a well-bonded interface with no visible defects was formed.
