Abstract

In the realm of advanced materials engineering, the development of hybrid nanocomposites has garnered significant attention due to their superior mechanical properties and potential applications. The primary aim of this research is to develop a surface hybrid nanocomposite using Al1050 aluminium alloy (5 mm thickness) as the base material through friction stir processing. B2O3 nano-powder, averaging 100 nm in size, and Cu micro-powder, averaging 5 μm in size, were incorporated into the aluminium surface in various volume ratios using the Friction Stir Processing (FSP). The processing parameters included a tool rotational speed of 1250 rpm, a feed rate of 50 mm min−1, and a tilt angle of 3°. The number of passes was set at two levels: 1 and 3 passes. The influence of the volume ratio of constituents and the number of passes on the microstructure and mechanical properties of the resulting composite was thoroughly explored. The samples underwent tensile tests, microhardness tests, and metallographic examinations using both Optical Microscopy (OM) and Field Emission Scanning Electron Microscopy (FE-SEM). The composite with 25%-B2O3-75%-Cu composition exhibited the highest stress and hardness values, measuring 139 MPa and 58.14 HV, respectively. The enhanced strength of this sample is attributed to the presence of additives and the resultant grain size.

利用搅拌摩擦加工技术制备的 Al1050/B2O3+Cu 混合表面纳米复合材料的微观结构和力学特性
在先进材料工程领域,混合纳米复合材料因其优越的机械性能和潜在应用而备受关注。本研究的主要目的是以 Al1050 铝合金(厚度为 5 毫米)为基材,通过搅拌摩擦加工技术开发一种表面混合纳米复合材料。通过摩擦搅拌加工(FSP)将平均尺寸为 100 纳米的 B2O3 纳米粉体和平均尺寸为 5 微米的铜微粉以不同的体积比加入铝表面。加工参数包括工具转速 1250 rpm、进给速度 50 mm min-1、倾斜角度 3°。搅拌次数分为两级:1 次和 3 次。研究人员深入探讨了成分体积比和加工次数对复合材料微观结构和机械性能的影响。使用光学显微镜(OM)和场发射扫描电子显微镜(FE-SEM)对样品进行了拉伸测试、显微硬度测试和金相检验。25%-B2O3-75%-Cu 复合材料的应力和硬度值最高,分别达到 139 兆帕和 58.14 HV。该样品强度的提高归功于添加剂的存在和由此产生的晶粒尺寸。
