The fly-ash produced in thermal power plants is a major pollutant to the air and soil. This paper designs a new composite material with the fly-ash as the reinforcement. For the composite, the AA 6061 aluminum alloy was taken as the matrix, Al2O3 as the primary reinforcement, and fly-ash as the secondary reinforcement. The microstructure and mechanical properties of the proposed composite were measured, and compared with those of previous experiments on AA 6061 alloy. The results show that the proposed composite achieves uniform distribution of Al2O3 and fly-ash in AA 6061 alloy; the mechanical characteristics like tensile strength and hardness were improved after adding Al2O3 and flyash; however, ductility and facture toughness were minimized after the addition. The research findings offer a new way to recycle the fly-ash generated in the thermal power industry.

“…Heat treatment can be also carried out to improve the mechanical properties. The stir-casting technique is even capable of fabricating AA 6061−B 4 C composites with very high B 4 C content up to 31% of weight fraction [ 43 ]. Vacuum stirring and the progressive addition of reinforcement were needed to incorporate a high content of B 4 C into matrix.…”

A Review on AA 6061 Metal Matrix Composites Produced by Stir Casting

In recent years, many alloys as well as composites of aluminium were developed for enhanced material performance. AA 6061 is an aluminium alloy that has extensive applications due to its superior material characteristics. It is a popular choice of matrix for aluminium matrix composite (AMC) fabrication. This study provides a review on AA 6061 aluminium alloy matrix composites produced through the stir-casting process. It focusses on conventional stir-casting fabrication, process parameters, various reinforcements used, and the mechanical properties of the AA 6061 composites. Several research studies indicated that the stir-casting method is widely used and suitable for fabricating AA 6061 composites with reinforcements such as SiC, B4C, Al2O3, TiC, as well as other inorganic, organic, hybrid, and nanomaterials. The majority of the studies showed that an increase in the reinforcement content enhanced the mechanical and tribological properties of the composites. Furthermore, hybrid composites showed better material properties than single reinforcement composites. The usage of industrial and agricultural residues in hybrid composites is also reported. Future studies could focus on the fabrication of AA 6061 nanocomposites through stir casting and their material characterisation, since they have great potential as advanced materials.

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

2020

View full text Add to dashboard Cite

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.
