A Critical Review on Synthesis of Aluminum Metallic Composites through Stir Casting: Challenges and Opportunities

Abstract

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.

Experimental Investigation on Tribological Behaviour of AA6066: HSS-Cu Hybrid Composite in Dry Sliding Condition

“…e specimen has a 20 mm diameter and a length of 110 mm. Similarly, the pure AA6066 alloy specimen was also prepared using the same method and same dimensions of the composite specimen preparation for the comparison perseverance [26][27][28].…”

Dry sliding wear response of aluminium matrix composites (AMCs): a critical review

“…Depending on the major alloying elements, there are several aluminium alloy groups (series) that offer greater flexibility for the selection of matrix material [7,13,14]. Among these alloy groups, medium strength (Al 5000 and 6000 series) and high strength (Al 2000 and 7000 series) alloys are commonly employed as the matrix material [15][16][17][18]. Table 1 lists the most common matrix materials used in the manufacture of Al-based composites.…”

Sliding wear response of ultrasonic-assisted stir-squeeze cast Al-Zn(-Mg) alloy/ZrO2p composite: wear mechanism and subsurface deformation

“…Aluminium alloys have emerged as new promising materials with potential applications in a variety of sectors such as automobiles, defense, aerospace, and other engineering fields due to their higher stiffness and specific strength, superior resistance to wear and seizure, and better-elevated temperature strength [1]. These innovative materials have acquired a lot of traction in the automotive industry in the last few years to improve fuel efficiency [2]. The effectiveness of many automotive parts is determined by their mechanical and tribological characteristics, such as hardness, wear, and frictional behavior.…”
