“…The intense stirring action during FSW and presence of nano-SiC particles resulted in severe plastic deformation resulting in increased hardness at the nugget. Moreover, nano-SiC particle addition resulted in grain boundary pinning [35]. The minimum hardness value was found at HAZ.…”

“…The tensile and yield strength was observed to increase with the wt% of nano-SiC particles. The increase in the 5 Journal of Nanomaterials mechanical strength of the weld joint with the increase in the wt% of nano-SiC is credited to the increased material mixing between the base metal and the reinforcement, which led to the accumulation of large amounts of reinforcement particles at the grain boundaries due to decreased dislocation during dynamic recrystallization [35].…”

Friction stir welding (FSW) is a solid-state technique used to join Al-Zn-Mg alloys effectively compared with other conventional welding methods. Al-Zn-Mg alloy was processed for welding because they significantly demanded various engineering applications. A novel method of this research work is to characterize the unique mechanical properties of Al-Zn-Mg alloy reinforced with 1 to 3 wt% of nano silicon carbide (nano-SiC) particles developed by novel interlock friction-stir welding. The process parameters chosen for welding are rotational tool speed 1100 rpm, weld speed 25 mm/min, and triangular pin profile. The weld joint properties such as tensile strength, yield strength, and hardness were tested per ASTM standard. The microstructure of weld joints was studied with XRD and optical and scanning electron microscopy. The existence of silica particles in the weld joints and uniformed and homogeneous distribution of the particulates in the weld was verified by EDS analysis and microstructure. Al-Zn-Mg reinforced with nano-SiC joints has better static properties due to intensive softening in the stir region. Al-Zn-Mg with 3 wt% nano-SiC exhibits maximum tensile strength, yield strength, and nugget hardness of 191 MPa, 165 MPa, and 171 HV. Weld microstructures showed a pinning mechanism because nano-SiC particles were used as reinforcement during friction stir welding.

“…ND/(111) orientation is reduced as cold reduction increases, resulting in texture described by ND/(110) orientation [53]. Despite the same misorientation between grains, the misorientation distribution inside differently oriented grains was different, as determined by EBSD analysis [54]. Zinno et al presented an equal little standard subset calculation for the age of differential synthetic aperture radar interferometry distortion guides, and time arrangement appeared.…”

Light metal alloys are extensively used in automotive, aerospace, aircraft, and military sectors since their lightweight leads to reduced energy consumption, increased fuel efficiency, and better environmental protection. In the present situation, nanomaterials are the potential candidate for weight saving in the structural application and can meet stringent government norms. Nanomaterial was heat-treated in the furnace to about a certain temperature and time and then normalized for strengthening. The heat-treated nanomaterial undergoes different forging processes, namely, hot forging and cold forging, using a certain capacity’s hydraulic press. Hence, in this work, an extensive study on the influence of the prestrain annealing, the corrosion rate on differently treated samples, and the effect of sensitization heat treatment on the nanomaterial was done.

“…Moreover, the mechanical property of rolled and T 6treated AA7075 alloy was studied by incorporating various filler materials independently [52]. To do this, filler reinforcements (SiC, with a grain size of 25 μm, Cu, with a particle size of 10-20 μm, and MWCNTs having a respective mean length and diameter of 5 μm and 15-20 μm) were incorporated into the base matrix (cylindrical holes with 3 and 2 mm depth and diameter, respectively).…”

Processing methods of aluminium matrix composites (AMCs) are changing from time to time considering the ease of manufacturing and the final quality of the desired composite. The most well-known processing techniques of AMCs such as stir casting, powder metallurgy, spark plasma sintering, squeeze casting, friction stir processing, liquid metal infiltration, spray codeposition, and reactive in situ techniques were elaborated here with their respective distinguishing features and mechanical properties of the fabricated composites. Moreover, this review paper contains the factors affecting the mechanical properties of AMCs as well as their clear justifications. The mechanical properties of AMCs are highly affected by the type of processing method, process parameters, and type, size, and composition of the reinforcing material. Concerning this, the mechanical properties of aluminium and its alloys are highly improved by adding a variety of reinforcing materials in a broader spectrum.
