In the present study, industrial waste has been used as reinforcement in pure aluminium to enhance the physical and mechanical properties. This can be effectively obtained by the creation of Aluminium Metal Matrix Composites (AMMC). The present research work is focused on the synthesis of grinding sludge (GS) based AMMC by powder metallurgy. The composites contain pure Al matrix reinforced with three different weight percentages of grinding sludge constituents (6, 16 and 29 wt%). After that, the microstructure, density, hardness and compressive strength at room temperature are investigated. The presence of AlFe and AlFe₃ inter-metallic compounds has been examined using SEM (scanning electron microscope) area mapping and XRD (X-ray Diffraction). The density and hardness of composite materials were calculated for all samples. It is observed that the sample with 6 wt% GS sintered at a temperature of 700 °C shows 23% rise in compressive strength than that of the matrix when deformed to 48%. The strengthening mechanism of this sample indicates that the load-bearing, dislocation strengthening and phase transformation are the main contributors. The hardening behaviour based on the flow curves obtained from experiments has been studied using the Voce equation. Further, a modified Voce equation incorporating sintering temperature has been established for the Al/6 wt% GS composite material. This equation predicts the flow stress with good agreement to experimental flow stress concerning average absolute relative error (AARE) ranging from 0.37% to 4.44%.

在本研究中，工业废料已被用作纯铝的增强材料，以增强物理和机械性能。这可以通过创建铝金属基复合材料（AMMC）来有效地获得。目前的研究工作集中在通过粉末冶金法合成基于磨泥（GS）的AMMC。该复合材料包含纯铝基体，并用三种不同重量百分比的研磨污泥成分（6、16和29 wt％）进行了增强。之后，研究了室温下的显微组织，密度，硬度和抗压强度。AlFe和AlFe ₃的存在金属间化合物已使用SEM（扫描电子显微镜）面积图和XRD（X射线衍射）进行了检查。计算所有样品的复合材料的密度和硬度。可以看出，在700℃的温度下烧结了6％重量百分比的GS的样品，当变形为48％时，其抗压强度比基体的抗压强度提高了23％。该样品的强化机制表明，承重，位错强化和相变是主要的贡献者。已经使用Voce方程研究了基于从实验获得的流动曲线的硬化行为。此外，已经为Al / 6重量％GS复合材料建立了包含烧结温度的改进的Voce方程。
