“…Blade angle as 30 provides good level of axial flow and shearing action to such the solid particles into the melt from the melt surface and break the accumulation of mixing particles. Thus impeller blade angle 30 is suggested as optimal value to achieve homogeneous dispersion of reinforcements particles in the melt [2,12,13]. Stirrer size (d < 0.5 D) cause lack of suspension of particles at the center while stirrer size (d > 0.55 D) results particles concentrated at the center of the crucible base.…”

“…In case of hybrid aluminum matrix (HAMC) more than one reinforcements are added in aluminum matrix. Particles reinforced aluminum matrix composites are used in aerospace, automobile and structural application due very high strength to weight ratio, superior wear resistance, high stiffness, higher fatigue resistance controlled co-efficient of thermal expansion and better stability at elevated temperature, high thermal and electrical conductivity compared to conventional metals and alloys, which makes it suitable for design of an extensive range of components in advanced applications [1,2,[4][5][6][7]. Selection of processing of technique plays a vital role over the property of the composite.…”

Aluminum matrix composites (AMCs) and hybrid aluminum matrix composites (HAMCs) becomes choice for automobile and aerospace industries due to its tunable mechanical properties such as very high strength to weight ratio, superior wear resistance, greater stiffness, better fatigue resistance, controlled co-efficient of thermal expansion and good stability at elevated temperature. Stir casting is an appropriate method for composite fabrication and widely used industrial fabrication of AMCs and HAMCs due to flexibility, cost-effectiveness and best suitable for mass production. Distribution of the reinforcement particles in the final prepared composite regulates the anticipated properties of AMCs and HAMCs. However, distribution of reinforcements is governed by stirring process parameters. The study of effect of stirring parameters in the particle distribution and optimal selection of these is still a challenge for the ever-growing industries and research. In this chapter accurate and precise attempts were taken to explore the effect of stirring parameters in stir casting process rigorously. Further, Optimal values of stirring parameters were suggested which may be helpful for the researchers for the development of AMCs and HAMCs. This chapter may also provide a better vision towards the selection of stirring parameters for industrial production of AMCs and HAMCs comprising superior mechanical properties.

Achieving the uniform distribution of reinforcement particles in MMCs is very important for the effect of stirring parameters and the flow action of the melt, which should be known. The effect of stirring parameters on the distribution of SiC particles in SiCp/A356 composites was studied by the experimental and numerical methods in this paper. The experimental results show the SiC distribution with different stirring parameters. In addition, the effects of the fluid velocity and volume fraction of SiC particle at different position of crucible on the SiC distribution were analyzed by numerical simulation. The velocity magnitude, axial velocity, and radial velocity were analyzed to explain theoretically the particle distribution. The shearing force, moments, and stirring power of the stirring rod were simulated based on CFD code. The numerical results show that the stirring temperature is lower, the shearing force is greater, the stirring time is longer, and particle dispersion gets better. On the other hand, the higher the stirring speed is, the more uniform the radial and axial flow are, and the better the particles were dispersed. The numerical results were in good agreement with the experimental data.

Aluminum metallic composites (AMCs) have been recognized as promising material exhibiting excellent functional and structural properties that can be significantly tailored to meet the industrial demands as well as to meet the design criteria for many applications such as aerospace, automobiles, marine, defense, and so on. Herein, an effort is made to provide an extensive overview of the various processing techniques adopted for the development of AMCs. Various processing kinetics of stir casting technique are elaborated comprehensively in terms of existing challenges, conceivable modifications incorporated in it. Considering the critical assessment on mechanical properties made through various kinds of literature, an electromagnetic stir-squeeze casting synergically equipped with ultrasonic transducing probe and bottom pouring attachments is recommended as the most appropriate processing technique for the development of AMCs. Moreover, appropriate recommendations regarding process variables and additives/modifiers, and potential future research opportunities are also addressed significantly to encourage the ongoing and upcoming researchers, which lead this critical Review toward novelty and uniqueness.
