A comparative study using silicon carbide and zirconium dioxide nano material’s to improve the mechanical properties of 6261AA

Abstract

The applications of nanotechnology differ in different areas of life. Despite all the advantages of nano-materials, there are many difficulties that need further research the most important of which is obtaining cheap, practical materials with appropriate specifications for use in various applications. This study examines the addition of multiple proportions of two materials (Silicon Carbide and Zirconia) to 6261 Aluminum alloy. Results were obtained stating that using the two nano-materials together is better than using each one separately. The best ultimate tensile strength (UTS)waders were obtained at (1.5-2.0 wt%)ratios ranging. 1.5% wt. of ZrO2 and (%SiC+% ZrO2).The improvements were (75.1 %) and (92 %) respectively. The UTS improvements (84.3%) for Al/ 2.0wt. %SiC. Also, a significant improvement was seen in the hardness values for all the weight ratios of the nano-additives with respect to the base alloy. The percentage of ductility has decreased after adding nano-materials.
