Characteristics of A6061/(Glass Fibre + AL₂O₃ + SiC + B₄C) Reinforced Hybrid Composite Prepared through STIR Casting

Abstract

In this article, A6061 and its reinforcement particles like aluminium oxide/glass fibres/SiCp/B4C (4% and 5%) with mixed composite and aluminium oxide/SiCp/B4C mixed without glass fibre composite are produced with different proportions using the stir casting method. Here, some experimental study is carried out on the composite layer through scanning electron microscopy and XRD test to show the influence of the reinforcement on A6061, and the percentage of gold-silver-copper (AuAgCu), aluminium-zinc (ZA), and palladium deuteride is increased in this composition and justified through the graphical representation of the XRD image. Mechanical properties of the stir casting composites were evaluated through microhardness, wear test under 200 rpm and 300 rpm and 20 N and 50 N, and tensile tests. The results were compared with the properties of the base metal, with glass fibre reinforcement specimen and without adding glass fibre specimen; this will help us to check the strength and weakness of the glass fibres in A6061.

Analysing the Mechanical Properties and Corrosion Phenomenon of Reinforced Metal Matrix Composite

“…A6061 with 95%, and 96%,). (Graphite, aluminum oxide, silicon carbide and boron carbide) 2.5 to 20 microns size of the reinforcements were preheated at a predetermined temperature from 250º to 550º Celsius for 30 min keeping in mind the end goal to expel dampness or some other gases introduced inside the support 18,19 .…”

“…Fortifications are poured physically with the assistance of a tapered container 18,19 . Mixing up the liquid aluminium with reinforcements at a steady rate which upgrades the uniform appropriation all through the matrix stage which is important to bordering the fortifications with the network material.…”

“…The Brinell hardness test is carried out to get to know the effect of the A6061 on the composites generated (Graphite, aluminium oxide, silicon carbide and boron carbide) in matrix material. The polished specimens were tested with the HBW micro durability tester and the values are depicted and shown below in Table 1 [16][17][18][19][20][21] . here the higher percentage (5%) gives a positive sign of hardness property in the prepared sample [18][19][20][21] .…”

A review on primary synthesis and secondary treatment of aluminium matrix composites

“…Silicon carbide is one of the widely used reinforcement materials as it improves the tensile strength, hardness, density and wear resistance of aluminium (Ramnath et al, 2014). Reinforcement using alumina improves the compressive strength and wear resistance of aluminium and its alloys while B 4 C reinforcement yields high elastic modulus and fracture toughness but with insignificant improvement in the wear resistance (Ipekoglu, Nekouyan, Albayrak, & Altintas, 2017;Khodabakhshi, Gerlich, & Worswick, 2018;Kishore Babu et al, 2017;Nanjan & Janakiram, 2019;Palanikumar, Rajkumar, & Pitchandi, 2019;Tiku, Navin, & Kurchania, 2020). The use of fibres as reinforcement materials improves the strength and other properties of the aluminium.…”
