“…This sandwich-like structure provides a unique combination of properties, making ACMs highly versatile and widely used in various industries [13]. ACMs offer exceptional strength-to-weight ratio, making them lightweight yet strong, suitable for applications requiring structural integrity while minimizing weight, such as building facades, signage, and transportation components [14][15][16]. Additionally, ACMs provide excellent flatness and rigidity, allowing for ease of fabrication and installation, even in large panels or complex shapes.…”

In the realm of composite manufacturing, this study delves into the innovative approach of enhancing Aluminum-Based Composite Manufacturing through Si3N4 Reinforcement leveraged via Friction Stir Process (FSP). The FSP technique, executed with precision using a vertical milling machine, intricately fabricates composite materials with unparalleled properties. Meticulously chosen parameters including pin diameter, tool tilt angle, and tool profile, coupled with precise tool traversal and rotation, define the operation. The composite substrate, composed of AA 2024, undergoes stringent cleanliness protocols before Si3N4 powders are strategically placed into a designated groove on the titanium surface for processing. Microscopic examination reveals the uniform dispersion of Si3N4 particles within the aluminum matrix, profoundly enhancing mechanical properties. The tensile strength experiences a remarkable 21.45% improvement, while hardness witnesses a significant enhancement of 36.9%. Additionally, fatigue strength is notably improved by 24.12%, and wear resistance sees a substantial boost of 30.44% following Si3N4 nanoparticle integration via FSP.

“…The FSP is used to reinforce Silicon Nitride (Si 3 N 4 ) and Aluminum Nitride (AlN) with the base metal Al2024. By eliminating flaws caused by metal melting, the hardness, corrosion resistance, microstructure formation, wear resistance, and durability of Al2024 were improved [14]. FSP used Al 2 O 3 micro and nanoparticles to strengthen the Al356 alloy surface.…”

Surface composites are viable choices for various applications in the aerospace and automotive industries. Friction Stir Processing (FSP) is a promising method for fabricating surface composites. Aluminum Hybrid Surface Composites (AHSC) are fabricated using the FSP to strengthen a hybrid mixture prepared with equal parts of Boron carbide (B4C), Silicon Carbide (SiC), and Calcium Carbonate (CaCO3) particles. Different hybrid reinforcement weight percentages (reinforcement content of 5% (T1), 10% (T2), and 15% (T3)) were used in fabricating AHSC samples. Furthermore, different mechanical tests were performed on hybrid surface composite samples with different weight percentages of the reinforcements. Dry sliding wear assessments were performed in standard pin-on-disc apparatus as per ASTM G99 guidelines to estimate wear rates. The presence of reinforcement contents and dislocation behavior was investigated using Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) studies. The results indicated that the Ultimate Tensile Strength (UTS) of sample T3 exhibited 62.63% and 15.17% higher than that of samples T1 and T2, respectively, while the Elongation (%) of T3 exhibited 38.46% and 15.38% lower than that of samples T1 and T2, respectively. Moreover, it was found that the hardness of sample T3 increased in the stir zone compared to samples T1 and T2, owing to its higher brittle response. The higher brittle response of sample T3 compared to samples T1 and T2 was confirmed by the higher value of Young’s modulus and the lower value of Elongation (%).
