Development and Characterization of Mg 3zn 1cu 07Mn Alloy Reinforced with Hybrid Al2O3 Composites Through Powder Metallurgy

Abstract

The last decade has witnessed an advancement in the development of high-performance Magnesium (Mg) alloys in the cast and wrought form, composites based on Mg, and diverse processing techniques. Mg ion batteries and bioabsorbable Mg alloys are an example for it. Mg alloys containing rare earth elements such as Mg-Gd-Y-Zr alloys display very high heat resistance. Several low-cost Mg alloys like Mg-3.5Al-4.2La-0.3Mn, Mg-1Nd-1Ce-0.5Zn-Zr, etc., were developed, which is essential for expanding industrial applications of Mg-based alloys. Nowadays, many researchers focus on developing Mg alloys that display optimized mechanical characteristics with diand#64256;erent process parameters. Another domain where the progress has seen is in the Mg alloys reinforced with ceramic particles, carbon nanotubes (CNT), etc. Recently Mg alloys such as AZ31-Gd, Mg-Al-Pb-La, and Mg-Li-Al-Zn are used as the anode in the Mg-air batteries. newlineA large number of extensive studies have been conducted in the last decade to improve the mechanical character of Mg Metal Matrix Composites (MMC). There are several conventional and nonconventional techniques available for accommodating diand#64256;erent reinforcements along with the Mg metal matrix. The lack of mechanical properties of pure Mg metal can be resolve by suitable alloying elements. The properties of alloys can further increase by strengthening the alloy matrices with appropriate reinforcements and forming composites. Thus the application area of the Mg-based alloys and composites can be widened, and it can be utilized in structural applications, including automotive, aerospace, and biomedical sectors. The literature study shows that several eand#64256;orts have been made to improve the mechanical properties of the Mg composites by using diand#64256;erent types of reinforcements and varying its weight percentage and processing techniques. Mg matrix composites exhibit superior properties while reinforced with ceramic reinforcements such as Aluminium Oxide (Al2O3) newlineand Silicon Carbide (SiC). Even though, the addition of th
