摘要

近几十年来,轻质材料因其有效性而受到国际关注,工业部门是其主要用户。具有纳米杂化增强功能的金属基复合材料是一种独特的复合材料系统组合,可提高材料的机械性能。本文讨论了石墨烯纳米片(GNP)和二氧化钛(TiO2)增强的铝 7075 合金的力学性能,其增强剂的不同重量百分比是通过搅拌铸造技术制备的。1 wt.% GNP 和 3 wt.% TiO2 增强复合材料在所研究的增强范围内显示出最佳性能,拉伸强度提高了 71.9%,显微硬度提高了 86.6%;但与基合金相比,伸长率降低了 31.7%。0.5 wt.% GNP 与 1 wt.% TiO2 增强纳米杂化复合材料的韧性最大。XRD 结果显示了相分析。对断裂表面的 SEM 分析表明存在韧性断裂和脆性断裂。

Synergistic effect of graphene nanoplatelets and titanium dioxide nanopowder-reinforced aluminium nanohybrid composites on mechanical properties
Due to their effectiveness, lightweight materials have gained international attention in recent decades, with industrial sectors being the primary users of them. Metal matrix composites with nanohybrid reinforcement are a unique composite system combination that enhances the material’s mechanical qualities. In the present article, the mechanical properties of graphene nanoplatelets (GNP) and titanium dioxide (TiO2)-reinforced aluminium 7075 alloy are discussed with varying weight percentages of reinforcements prepared by the stir casting technique. 1 wt.% GNP with and 3 wt.% TiO2-reinforced composites show optimum properties within the range of reinforcement studied, with a 71.9% increment in tensile strength and an 86.6% improvement in microhardness observed; however, elongation is decreased by 31.7% in contrast to the base alloy. Maximum toughness is found to be in 0.5 wt.% GNP with 1 wt.% TiO2-reinforced nanohybrid composites. XRD results show phase analysis. SEM analysis of the fractured surface reveals a mixture of ductile and brittle fractures.
